James, I have to confirm that 'The Boeing 707 was a safer aircraft
because of the Comet experiences.' To set-up my Comet webpages I made a
lot of search and found out that during the accident investigation of YP
and YY there were regular safety meetings which were held between DH and
Boeing. The philosophy was (and is the same today) that competition
stops when safety is the main focus. Boeing was well informed about the
investigations and the related findings, so that results could already
be implemented in the 07 design. I would say that the 07 was the first
a/c to benefit from the negative DH experience. Of course Boeing had
already experience as you state, they didn't start from scratch.

You should say : Boeing already knew from other experience and in
addition had the results of the negative Comet experience.

Let's try to be objective ...
