Well I used to watch a few ACI programmes, I posted about it a while ago but there was a rather odd crash which happened in Greece a few years ago.
Helios flight 522:
Helios was a small airline based in Cyprus. Helios Airlines went bankrupt in 2005, After losing one of its small Fleet of 3 737's to a tragic air disaster.
One of the most mysterious flight accidents in aviation history, One of the 3 Helios 737's was en route from Cyprus to Prague via Athens when it failed to communicate with ATC for more than 2 hours, which was much longer than its origional flightplan. The aircraft circled over Athens and the Greek air force flew alongside it to try to establish communications with them and to their astonishment- there was no sign of life whatsoever including in the cockpit where the pilots appeared to be asleep as they did not even turn their head to the military aircrafts flying closely- Likewise in the cabin of the 737. Amazingly, they noticed a male figure walk into the cockpit in steward clothing and he did not seem too bothered by the military being so close, and did not make an attempt to contact through radio. One military pilot put his hand up clearly at the steward, but he did not respond for a while untill he did it back. The plane remained circling a small hill range outside Athens and ran out of fuel, slowly descending into the valleyside killing everyone on board (although some conspiracies assume they were already dead).
The incident was traced by observing wreckage of the cockpit equipment, when they discovered that the ground crew had adjusted the cabin oxygen supply during maintainence as they checked a replacement cabin door for its airtight structure (as an incident previously caused the replacement of a door). The warning alarms were sounded multiple times in the cockpit and help was given via ATC, but the crew failed to locate the problem as standard procedure rarely checks the use of the cabin oxygen supply, as 99.9% of the time it is set to "Auto" and nothing else. As the gas masks dropped in the cabin, the oxygen is designed to supply passengers for a few minutes while the pilots descend to a safe breathing altitude. But as there was no sign of cabin pressure loss, the pilots never descended untill all inside had passed out (except one male steward, who remained breathing off portable oxygen located in various locations around the aircraft, but he was likely highly nauseated and hardly concious enough to act efficiently). The loss of the small Cypriot airline sparked a wave of sadness throughout the Mediterranean island.
