How many versions?

I like the episode on the Tenerife disaster, but I've seen 3 different versions of it. There's the Mayday episode, and there's the one-hour 'Nova' episode, which I bought on dvd, thinking it was the same one I'd seen on Mayday. It was basically the same, with the same actors and same re-enactment, but slightly different in their choice of material. I seem to recall that there were more interviews with the passengers giving their recollections of their experiences, and less emphasis on the investigators and experts who took over to find out why the collision had happened.

Then there was an unusual version that I saw once on the Discovery Channel - a 90 minute expanded version that contained footage neither of the other two episodes did. I remember an interview with the Dutch captain's daughter, describing her father's personality, which did have a certain bearing on the events, as he was rather a stern, dominating type whom the subordinate officers felt timid about challenging. And there was also a scene where the flight attendants were flinching at the necessity of giving him the bad news that some passengers were missing in the terminal, delaying them from departing - I remember the captain YELLING into his radio receiver at the poor woman, demonstrating again that he was a difficult person to deal with, and his crew were intimidated by him.

Has anyone else seen this 90-minute version? It's really quite good, and I've been hoping to see it again, but it's not a regular "Mayday" episode, and seems to have been a special put together to be shown independently.

Flat, drab passion meanders across the screen!
