Not certain about the F4 QRA days, but Leeming F3's once launched 8 on Q with double figures being attained/supplemented by a KC10, a Nimrod and a C130.
God knows how many Bears' crossed the line in a mega-formation before re-appearing from (the then) 'black hole' before splitting and spreading out to every point of the compass.
AFAIR late '80's.
As an aside, Q3 (at RS30) never managed to launch at all. Tech problems.
In the end L fits' (minus the 2,2+4) made up Q7 and Q8.
An amazing day in the Q world.
