The "Should he" discussion has been done to death on R&N. there are valid points for boths views. The basic fact is, what's done is done. He took it, and filmed. The footage may help in some way, and yes it's possible it hindered. Nothing can change that now.
People died, everyone did what they thought was best at the time. Let's not underestimate the effects of shock, injuries etc.
Anyone criticising FAs (as some implied on other thread), as Oz said, you can see them assisting in the footage. I'
m also sure (as I've said in another post on R&N) that you can see one of the FAs running BACK to the wreckage, after she is about 100m away. Brave, especially if you're hurt yourself.
Will be interesting to see what, if anything, the investigations from the local end find out/reveal to the world.
