In '64 I was on a Vixen squadron on HMS Centaur during confrontation and we were briefed by the squadron AWI on how to shoot down an Indon. P51 with 2 inch rockets. It required the P51 to fly straight and level while the looker (me) consulted the tables to work out the gravity-drop/range etc. This produced a hilarious reaction, and the best option seemed to be to overtake the P51 and jettison the droptanks on top of him!
Of course several years before our "experts/leaders" had decided that a gun was not really necessary in a fighter any more!!! I'd rather have one engine and two guns than two engines and no guns!
I then went on to the Lightning F3!!!
