Some of the non-pilots who have been reading about this accident seem to be having difficulty in working out just why the pilots amongst us are so horrified by what appears to have happened.
It is the very basic need to "watch the shop", for at least one of the pilots to be keeping an eye on the instrument panel, that very quickly becomes second nature.
I can only describe what went on, in non-aviation terms, as having increased ones speed when driving to say 70 mph - and then closing ones eyes! And waiting for the bang.
If someone had told me that an accident like this would one day take place, well, I just wouldn't have believed them!
