Victor 1s at Tengah only tried to take off early in the day. The next task was to send someone out to untangle the upwind arrester barrier, which obviously had to be in the down position for the takeoff. They used almost all of Tengah's 9,000 ft.
Thanks for clarification of Waddington's Q arrangements. That task had long gone by the time I got there (1981), so everything 'launched' from the various Sqn Dispersals (B, C, D, E). during Exercises. Any extra aircraft generated would usually be on A, while F remained usually empty for visiting ac.
