Nimrod crews are all cowards, basically:-
"The misreporting of surface contacts was caused by the Nimrod’s reluctance to probe any of its radar contacts visually for fear of being shot down. Its much-vaunted radar, though excellent at detection, was dangerously misleading in target classification. At Ascension Island, there were no Nimrods available to sanitize the sea areas until well after the Task Force had proceeded south. When they did arrive, they carried out missions around Ascension but on only two occasions did they venture up to 600nms south of the Island. That was well short of the 3,800 nm to the Falklands Exclusion Zone. The Nimrods refused to enter areas where there was any chance of being detected and attacked by Argentine fighter aircraft. This effectively reduced their value to our surface and submarine commanders to zero and occasionally continued to work to Argentine advantage through misclassification of radar contacts."
