I stand corrected - sincere apologies.
Perhaps I should have been more succinct:
There are 2 SeaKings in the world:
Sikorsky and Westland.
These two versions are like chalk and cheese is what I should have said.
The differences are (to name a few) with engines/electrics/governors/dimensions/gearbox.
Would still love to know why the cab "tipped forward". Unless the pilot did it it can surely only be a runaway fwd in pitch?
