Greek Crash Tragedy

The crash of Helios ZU552 was a tragedy and like all such tragedies has occupied the mainstream media 24/7. Initial reports claimed that an SMS sent from the doomed aircraft stating that the pilot had turned blue and they were freezing turned out to be a hoax with the claimant subsequently being arrested by Greek police.
After reading several different media accounts of the doomed aircrafts last moments some serious factual discrepancies exist.
In this news report it is claimed that shortly after takeoff a crew member advised the control tower that there was a problem with the airconditioning. Radio contact was lost soon after this communication and two F16s were scrambled to investigate. As is standard operating procedure the two fighters attempted to get the commuter jet to follow them to an airport to land but it did not follow and subsequently crashed.
This news report is similar but claims that the F16 pilots saw oxygen masks had been deployed and that the plane was making continuous right-hand turns to show that it had lost radio contact.
Both of the above news reports state that in the cockpit the captain was not visible, the copilot was slumped in his chair and two unidentified people appeared to be trying to take control of the aircraft. This visual contact by the F16's was supposedly made at an altitude of 34,000 feet (10 kilometres).
The above data has made me wonder the following;

  • Why had the captain left the cockpit during an emergency situation?

  • Why did the pilots not descend to a survivable altitude? The fact that two people were apparently seen in the cockpit minutes before the crash would seem to indicate that the dial on the autopilot could have been changed by crew immediately upon loss of cabin pressure

  • Can you send SMS messages from mobile phones at high altitudes as there appear to be claims coming out now that several SMS messages were received by friends/family of passengers? and if so, why no actual voice calls?

  • According to this report about the Payne Stewart accident his planes windows were obscured by frost which is supposedly consistent with decompression at high altitude, so how did the F16 pilots see what has been reported?


NEWSFLASH: According to this breaking story there is NO black box recorder. They have found the recorder casing but the contents have apparently disappeared (been ejected is the story). If anybody out there who knows about black box recorders can tell me if this is a common occurence let me know at this email address.
