I don't think flipster claimed that and we have had many a conversation on the subject.
By the time the Vietnam lessons were being learned the C130Ks had been delivered. If you wind back the clock to the late '60s it was the UK leading on ESF and had fitted it to the first trial installation aircraft at Lyneham.
Anyway, we digress and probably goes to show the importance of well-documented inquests and enquiries to avoid the facts being clouded.
