I've just read a rather disturbing piece on BBC News claiming a 1 in a billion chance for another Concorde accident. The story is at
http://news.bbc.co.uk/hi/english/uk/...00/1528972.stm
Presumably this is just the BBC reporter being sloppy and they are referring to the particular accident, but quoting these sort of odds fills me with disbelief. I remember very well NASA quoting a million to one chance of a catastrophic Shuttle failure, shortly followed by Challenger exploding. Richard Feynmann took a rather independent view of that one and estimated 1 in 100.
Good BBC2 programme too, IMHO.
