Im trying to remember which prop job in the 1950s kept going
down...British aircraft IRRC....which had the tails snapping
off...some sort of metal fatigue/harmonics issue which took them
awhile to find and correct. They did a movie about it in the 1960s
IRRC

Turbojet, but maybe this one?

They didn't understand metal fatigue very well in those days- nice big
square windows in the early models.

It wasn't the fuselage windows for the passengers that caused the
problem (at least for G-ALYP), it was the ADF window in the roof. The
passenger windows did fail in the tank test though. The stresses at the
corners turned out to be higher then de Havilland's engineers had suspected.http://www.oocities.org/capecanavera...cogalyp.htm#yy

I see they later made the naval versions with fewer windows. *Renamed
as an MR.2P, one was shown crashing into a lake near Toronto 10 or so
years ago.

This aircraft has been flying since 1967, and has given excellent
service.

But you post a fatal crash video you found on the first page of
google
returns.

Bah!

Right, thanks for that. That aircraft is supposed to scour the water
for enemy craft. That is its specialty. So crashing in a friendly
lake full of civilians on a bright sunny day isn't exactly the first
think you'd expect from that "service".
It was an "air show" - the MOST dangerous aviation activity, short
of all-out war.
