IIRC: 2 comets were lost at takeoff DeH introduced fixes.
They lost 2 more in flight and introduced fixes for anything they could think of. After the 3rd in flight hull loss, they tried the water tank. ( I might have one to many in there??)
Even though this looks like a "best guess" kind of fix, it includes measures to prevent hull loss in the event of another failure. So it will either:
1) not happen again
2) happen again to a random a/c
3) happen again to the same a/c
If 3 happens, it will turn out to be something "goofy" like bad bonding in the HF radio system or antenna.
my 2 cents, and overpriced at that!
