There was a day in the late 70s when we went well into double figures.
The Russians sent a stream of Bear Ds and fs down into thew north atlantic.
LU scrmabled the Northern QRA, followed by Southern QRA. LU then generated as many jets as they could and CY generated all their qualified crews/jets and flew them to LU to turnround and go on state. As they started running out WT generated their F6 jets and likewise forwarded deployed them to LU.
IIRC, around 10 minutes after the last possible Q jet got airborne out of LU..... the next Bear in the stream turned round and went home........
