I do wonder why the false canopy is not used more often, as I have heard it can be a very useful device. The only other regular use of it is on the Canadian CF-18.
A serious question, and one which has often puzzled me: back when they did the trials at Chivenor of different colours on the Hawks the overall black came back as the one with highest visibility. Granted, when seen against the sky. But in what way is it more effective than the old red/white/grey scheme when seen against terrain, and if was so good why did some aircraft (Dominies and ETPS Alpha Jets) receive white wingtips? It has bugged me ever since the decision was announced, and I still can't see it (pun not intended).
Mind, I still think trainers should be all yellow, or silver with yellow stripes...
