What has happened to Steve Fossett - the aviator who went missing two weeks ago - it is thought somewhere in Nevada while flying his light aircraft - a plane like this one:http://en.wikipedia.org/wiki/8KCAB_Decathlon He spoke on his radio about half way through his fuel load and when he was just south of Walker Lake.Did he run out of fuel,did his airplane explode,did turbulence from the nearby Sierra Nevada mountains force him to crash,is sabotage a possibility,a heart attack or stroke at altitude,could the sun have got in his eyes and made him hit something,a strike by wild birds,did he have problems switching fuel tanks (John Denver died switching fuel tanks),did the fact that he didn't file a flight plan mean he was going to be flying over territory he was familiar with from previous flights.,Why didn't the emergency beacon on the airplane activate -was it blown up by an explosion,did it have flat batteries,could the beacon be working in a deep ravine but with a beam too narrow to reach available satellites,are weather conditions in the upper atmosphere inhibiting the signal,did fossett manage to land the airplane gently and then perish afterwards ( could he still be alive and if so why hasn't he sent a signal of some kind ),is the airplane under water,snow,mud,are the satellites working properly, was he hit by lightening,a microburst (sudden downdraft of cold air)could someone in a signal detection centre be receiving the beacon signal but deliberately ignoring it!? Is the computer software that alerts rescue service operators of the signal from the older type of beacon Fossett is believed to have on his airplane faulty? Have similar beacons successfully alerted the rescue services recently? Was Fossett's airplane suitable for flying over the terrain he was crossing and as someone who takes risks could he have been pushing his airplane too hard? Is it possible he got lost in mist and had a faulty instrument panel.Are there any unusual magnetic anomalies in the rocks in Nevada that could have thrown his compass off course? The fact that he didn't radio for help suggests that there wasn't much time before he hit the ground.Or was he behind a mountain and out of radio contact? How far away can an airplane be heard by the human ear - this could narrow down possible crash sites.Why have people checked the satellite images of Nevada and not found anything - is the airplane in pieces that are too small to be seen,are the pieces hidden by trees (which are changing colour for Fall),are the people looking at the satellite images too inexpert to be able to identify the parts of a crashed airplane.Are the satellite images of insufficient resolution,or perhaps they are not even covering the right area and Fossett did not fly where he would be reasonably expected to fly.What do you think?
