Thanks for the reference, They Gave Me a Seafire is a brilliant book which is available on Kindle. Cdr Crossley explains the Seafire saga which began with a strengthened Spitfire and arrester hook which accentuated that wonderful aircraft's CG problems. Measures to cope with these problems included an elevator bobweight which produced even more difficulties, all combining to claim the lives of several of his comrades. Too long to cover in the depth it deserves but those interested will find it fascinating. Operating such beasts on land would have worried me, but anyone who lands anything on a carrier has my fullest admiration, all honours to the Fleet Air Arm!
