Sorry crab, I don't really have a downer on you, just couldnt resist!
it's called banter, no problem
If you want to see a public sense of humour failure, look at the last post in the '2 helos collide in NZ' thread where the OP throws his teddies clean out of the cot, probably dropping the big chips on his shoulders in the process
Back to the thread and we do seem to have an over-reliance on automation and computer control to makes things easier for humans but we seem prone to assuming that such automation is fail-safe. In the AF447's crash, the computer tried to do what it was programmed to but 'garbage in garbage out' (no speed information) meant that it was up to the humans to save the day.
Unfortunately it was the wrong humans with the wrong mental picture of what was happening and a suspension of logical thought and action due to fear.
