Wasnt the latest version of the sidewinder decisive in the Falklands?Yep, I was thinking the exact same thing whilst reading the first part - great anecdote indeed Greyman. That's pilot factor.
One example that springs to mind is when the RN went to war with Sea Harriers against the Argentine Mirages, before the war, few thought the Sea Harrier could do the job, but in the right hands with the right training and tactics, it could. Although the Sea Harrier was a terrific mount and ideal for what the Brits needed, I'm also certain that had the British had Mirages and the Argies had Sea Harriers, the result would have been the same.
