The Chinook, in my opinion, has always been a bloody dangerous airframe
At one moment during a Chinook HC2 differences course at Odiham in Feb 1994, I felt, for the only time in my life,
my hair stand on end.
Luckily that 1994 posting involved only one 'new' HC2 airframe and it was easily possible to keep it firmly on the ground, due various 'airframe rigging' problems, for several months of a very long 6 month tour.
