Well, I've cleared a fair number for take-off from 09L (and 10L before that) but they weren't too frequent.. One reason for not using 09L for take off, way back long ago, was the presence of a Marconi S264 radar antenna close to the holding point.
The old route from the A and B cul-de-sacs to 09R was via the inner, west about. If there was a gap in the landers we'd sneak the odd BAC-111 away from Block 11 (God only knows what that is called now).
