A full fig Vulcan attack, never actually practised had No 1 fly straight through, No 2 45 deg crossing 30 seconds later, No 3 45 deg from the other side. Finally No 4 straight through.
Had it all worked 40 tons in 90 seconds would have been a bit noisy. I haven't looked at the fall out for the following aircraft. The nearest we got was 3 aircraft in trail, 2 mile separation in simulated night over a route in Libya.
