Imagine coming back from a camping trip in the desert. Then a few months later you notice in your photos from the trip that you camped inside a giant impact crater so big that no one documented it before. Could it happen?

During several trips to the Black Rock Desert, mostly while supporting the Stratofox Aerospace Tracking Team for suborbital space rocket launch efforts, Ian Kluft KO6YQ noticed some oddities in rock formations. He had a little experience with volcanoes, and some rocks in the area looked unusual. There seemed to be some lava here and there – but where was the volcano? He observed that even a large caldera should have mostly volcanic rocks. He then noticed some curved geographic structures in satellite imagery which made him curious if it might be an impact crater.

A TV documentary about meteor impacts mentioned some characteristics of impact craters. He went to the Internet to learn more. He noticed some of his own pictures of the area had cone shaped structures which might be “shatter cones” due to an impact shock wave that passed through the rocks. Discussion with others produced suggestions and volunteers who joined the effort. More circular features in satellite photographs were found. Igneous dikes through white layers of rock had been described and were visible in many photos.

The possible impact crater is 30 miles (48 km) wide east-to-west and 40 miles (64 km) north-to-south centered around 40.984045 N, 118.916016 W. That is in northwestern Nevada halfway between Reno and the Oregon border. The apparent ancient geological structure is so old that much of it is eroded away. The forces that eroded the Black Rock Desert itself, whether glacier or stream, have apparently cut through the crater rims and floor to do it.

Following an expedition to the area in late January, more possible shatter cones were observed in one of the rock samples collected. These are only formed by the shock wave of an impact event or nuclear explosion. The nearest nuclear test was underground at Sand Springs Range in central Nevada. Atmospheric tests at the Nevada Test Site were at the southern, and opposite, end of the state. So that points toward an impact if confirmed. But professional geologists will want to have the final word on confirming them.

In addition to shatter cones, rock samples were thought to contain shocked quartz because the criss-cross fractures looked like examples in online documents. But this group of volunteers doesn’t have equipment for proper photography of shocked quartz. If found, that would be another way to prove the impact origin of the rocks.

Columnar jointed columns hundreds of feet tall appear on some bluffs in locations that appeared consistent with part of a slowly cooling crater floor. But that alone only helps as part of a bigger picture, because volcanoes can have lava cool in columnar joints as well.

They also found local geological studies which described oddities which could be explained by an impact event. Layers of rocks in the mining district called Sulphur left geologists with a mystery about the cause of chemical alterations since 1980. The group compared it with information in online geological texts like “Traces of Catastrophe” by Dr Bevan M French of the Smithsonian Institution. Layers of impact ejecta seemed to explain the rock layers better than the previous theory about acid uniformly cooking the rocks across the region, and only in one layer of rocks. A separate 1980 study 40 miles away identified an immense air-fall tuff layer in the Soldier Meadows area as having been deposited in a single unit, yet couldn’t locate the volcano which produced this enormous volume. Fault diagrams published online by a mining operation at Sulphur on the edge of the circular structure from the satellite photo also look like curved terraced faults in the wall of a crater.

The mining geologists who wrote papers from 1980 to 2002 had not mentioned the possibility of a crater. But they were each gathering single puzzling pieces of information. A larger image seemed to be forming when putting the pieces together. The group hopes the information will be helpful to geologists who do further work in the region.

The theory hasn’t been put to any test by professionals yet. Some responses point out that the elliptical region reported as the possible impact crater could also be the volcanic caldera that the 1980 study was looking for. If so, such a large volcanic caldera would still be a significant discovery for the region.

This will remain officially a mystery for a while until the professional geologists get to study it. There is a lot of information available online for those who are interested.

Following the Pilkhana massacre which occurred February 25 and 26 leaving 74 dead and the inferno at the Bashundhara City shopping mall complex March 13 leaving seven dead, Prime Minister Sheikh Hasina said security measures are being tightened countrywide across Bangladesh.

Fire drills will be enacted at all key-point installations (KPI). Fire fighting systems will be examined by the fire brigade and the public works department (PWD) to ensure functionality. Security measures will be enhanced supplementing areas under private security such as at the Bashundhara City Complex.

The Fire Service and Civil Defence Department requires modernization and needs new equipment to fight fires past the sixth floor of buildings. The Fire Brigade says it needs turntable ladders, snorkels, foam-tenders, lighting units, emergency tenders, fireproof uniforms, and rescue ropes for fire fighting and rescue operations. Transportation to fires is also an issue due to narrow roads, low electrical wires and congestion.

The Bangladesh National Building Code requires fire fighting equipment installed in buildings over seven floors. This code is to be monitored by authorities to ensure compliance with the new guidelines and to make sure buildings are being maintained.

The Bashundhara City Complex opened Monday for shoppers two days after Friday’s blaze. A probe is underway to determine the cause of the fire and to assess structural damage.

Loss of life was minimized as the blaze broke out on a Friday, the beginning of the weekend in Bangladesh, so offices in the upper floors were empty. The lower eight floors are used for shopping and the upper floors are all Bashundhara Group offices.

The mall is valued at Tk 7.0 billion (US$100 million). It is not known if the complex is covered by fire insurance.

It is estimated that it will take over two years to rebuild the area damaged by flames which were burned down to a skeleton. Bashundhara City’s technical advisor, Latifur Rahman, estimated damages at Tk 2.0 billion (US$29m).

Only one television cameraman has been allowed in to film the burnt area. None of the 2,500 shops, cinemas or cafes were burnt by the inferno. The seventh and eighth floors still experience smoke damage, and there was water damage to merchandise.

A three member committee is currently investigating the cause of the fire which will consist of Iqbal Khan Chowdhury, joint secretary of the ministry, representatives of the police, IGP Noor Muhammad, and fire brigade, Director General Abu Nayeem Md Shahidullah. The committee is required to report within the week with their findings. The forensics department is also sifting through the burnt remains.

The Dhaka Chamber of Commerce and Industries has also formed a committee which has begun interviewing witnesses and recording their testimony alongside the government committee.

It has been discovered that 150 closed circuit cameras were not being used when the fire started. Another mystery is why the mall fire fighting system has been found unused.

“In the shopping mall there is an ultra-technology elevator which runs even without electricity but we have found that locked,” Iqbal Khan Chowdhury, joint secretary (Police) of the home ministry, said. “Why the fire burnt so fiercely is a matter to think. We have to see if there was any incendiary substance there. These matters seem to be mysterious.”

Mall management has been asked to submit substances and items which would have been in the upper floors when the fire started. The fire erupted on the 17th floor and spread quickly to the two floors above and engulfed the three floors below. The aerial ladders belonging to the Fire Service and Civil Defence reached as high as the 13th floor of the 21-storey building.

Videos have been sent to the United States (US) for examination to assist in determining the cause of the fire and to help in the damage assessment. Experts from the US are expected to arrive soon.

Firefighters were brought to the rooftop of the 20-storey tower by helicopter. The only fatality in this operation was Baki Billa, a firefighter of Bashundhara City firefighting department, who fell when climbing down a rope from a helicopter to the roof of the building. Three other firefighters made the transition safely. At this same time, the chief security officer was safely rescued by the Bangladesh Air Force helicopter, a Bell 212. Six security officers of the complex also lost their lives.

Indonesian state-owned flag carrier Garuda Indonesia has been expanding, with the airline set to add nine new jets to its fleet and double its flights between Jakarta and Kuala Lumpur. Garuda is also considering a bid for defunct rival Linus Airways.

Garuda is expecting the imminent arrival of four new Airbus jets and five new Boeings. The Airbuses, A330-200s, are earmarked to fly international routes to Seoul and Shanghai starting in July. All four have Internet and telephone access for passengers. The Boeings, B737-800 Next Generation aircraft, are due to be in service by the 2010.

Also planned before the year’s end is the increase in flights on the Jakarta-Kuala Lumpur route from one to two per week. “We saw our current load factor[s] have reached 75 percent and even more during school breaks like June and July,” Said the company’s Vice President for Network Oversight, Risnandi. “This is very promising.”

Garuda is now reported to be considering a bid for Linus, who stopped operating on April 27 and have recently been stripped of the rights to fly their former routes as legally required for airlines that do not operate for more than thrity days. Linus still holds some documents of worth to Garuda for transfer to their subisidiary Citilink.

“I heard that Garuda intends to buy Linus who already hold an aviation business license (SIUP) and an air operators certificate (AOC) for the scheduled air services,” said Indonesian Director General of Civil aviation Herry Bakti S. Gumay to reporters for Bisnis Indonesia. He said that his office was in favour of a takeover by Garuda because foreign bids are limited to holding a maximum total of 49% of the shares in Linus.

Linus Airways’ President Directer Indra said that “we are flexible to acquisition, depending on the investor. If someone wants to buy 100% of the shares we can release our shares, but if someone wants take only a majority shareholding with us as a partner – we are also open.” Indra commented that he has had an informal meeting with Garuda CEO Emirsyah Satar but says that they never discussed acquisition by Garuda and that Linus is already in talks with another ‘strategic investor’ with a view to resuming operations.

Two airlines, Riau Airlines and Kartika Airlines, have both launched bids for the ten routes formally operated by Linus, which include four from Jakarta and three from Batam.

Garuda Indonesia’s Financial Direcotr Eddy Purwanto has anounced that US$650 million worth of loans from Bank Mandiri have been restructured. Garuda, who has apointed Rothschild’s as their international financial advisors, will now pay US$450 million by 2015.

An Atlas V rocket has successfully launched a classified spy satellite for the United States National Reconnaissance Office (NRO). The satellite, currently known to the public as NRO L-28, or Launch 28, is believed by amateur enthusiasts to be a signals intelligence (SIGINT) spacecraft, known by the codename Trumpet. The Atlas V carrier rocket flew in the 411 configutation, with a 4 metre diameter fairing, one solid rocket motor, and a single-engine Centaur upper stage.

The rocket lifted off from Vandenberg Air Force Base, Space Launch Complex 3 East (SLC-3E), at 10:02 GMT (03:02 local time) this morning. Today’s flight marks the thirteenth launch of the Atlas V, and the first Atlas V launch from Vandenberg. It is also the tenth orbital launch of 2008. The satellite entered a Molniya orbit, usually used by the NRO for SIGINT and communications satellites.

The launch was conducted by United Launch Alliance, a joint venture between Lockheed Martin, who designed and built the Atlas V, and Boeing, to provide EELV launches for the US Government. ULA president Michael Gass described the launch as “a proud moment in our company’s history”. The launch had been delayed by two years, from early 2006, due to a number of factors.

In addition to its reconnaissance payload, the satellite is carrying two small experiments. SBIRS-HEO 2 and TWINS-B. SBIRS is a test article for a missile detection system, slated to launch late this year or early next, and TWINS is a NASA infrared astronomy experiment. They will remain attached to the satellite for the duration of its mission.

Following the separation of the payload fairing, around five minutes after launch, all information on the launch was withheld, however about an hour into the flight, the launch was confirmed to have been successful. ULA will conduct its next launch on Saturday, when a Delta II will orbit a GPS satellite. The next Atlas launch is scheduled for mid-April, with the ICO G1 communication satellite.

Queen Elizabeth II, the British monarch, has today withdrawn and annulled a knighthood given to Fred Goodwin in 2004, heeding the advice given to her by a forfeiture committee. Goodwin is the former chief executive at the Royal Bank of Scotland Group (RBS) and was awarded his knighthood by the British government of the time for services to banking. The committee concluded “that widespread concerns about Fred Goodwin’s decision meant that the retention of a knighthood for services to banking could not be sustained.”

Goodwin was chief executive of RBS when they purchased ABN AMRO, a Netherlands bank, in 2007. The British government subsequently bailed out RBS for £45 billion, amidst the late-2000s financial crisis.

British prime minister David Cameron stated about the annulment: “The proper process has been followed and I think we’ve ended up with the right decision.” Cameron and Ed Miliband, UK Leader of the Opposition, both believed Goodwin’s knighthood should be removed. Miliband called it “the start of the change we need in our boardrooms.”

Liberal Democrat leader and Deputy PM Nick Clegg considered it to be the “right decision”. “[A]ppropriate” was the word George Osborne, Chancellor of the Exchequer used to describe it. “RBS came to symbolise everything that went wrong in the British economy in the last decade,” Osborne stated. Alex Salmond, First Minister of Scotland stated the title was given “for services to banking which could not therefore be sustained”, calling the decision “correct”.

Goodwin does not have the right to appeal against the decision, nor had the right to provide the forfeiture committee with any representations. The monarch holds sole responsibility for withdrawing all knighthoods; on this occasion Elizabeth II followed the advice of the committee, who decided to recommend the withdrawal to her. The Cabinet Office announced the advice had been given to the queen on the understanding that “Goodwin had brought the honours system in to disrepute”.

Speaking of the “exceptional case”, the committee explained: “In 2008, the government had to provide £20 billion of new equity to recapitalise RBS and ensure its survival and prevent the collapse of confidence in the British banking system. Subsequent increases in government capital have brought the total necessary injection of taxpayers’ money in RBS to £45.5 billion.” The committee understood that “Fred Goodwin was the dominant decision maker at RBS at the time.”

Until this announcement, criminal conviction and professional expulsion were the only causes for which individuals had their knighthoods revoked.
