I would imagine that their "discovery" is that metal fatigue set in around the square window frame and caused explosive decompression. Isn't it funny how DeHavilland and the investigators discovered this forty years before Channel 4.
Channel 4 also recently discovered that HMS Hood sank after taking a direct hit from a German naval shell in the main armoury; sadly about 50 years after the Admiralty worked that out by asking eye witnesses on other ships about what happened.
Apparently they are going to do a series of documentaries next year about how Channel 4 has just discovered the wheel, how to make fire and that ear wax tastes yukky.
