Chatting in the bar in the mess at RAF Leuchars in the 1970s (as you do) there was a lively discussion between Ltng, F4, Harr and Bucc crews about the qualities needed for a strike aircraft. One very senior and respected Flt Lt Harr pilot suggested the following: Twin engine, two crew, good load capacity, long range, low radar signature, manoeuverable, relatively cheap to produce, capable of about 500kts, good low level capability, able to absorb punishment. He said gentlemen, I give you the Mosquito with turboprops, modern avionics and systems. Everyone agreed.
