Take off ground roll of a B1 at Butterworth, with 35,000lbs bombs, 8050ft. Runway lenghth 8000ft, so lots of lights broken. To prove the first crew got it wrong the Detco then did the same take off. All figures good from ODM - actual ground roll 8050ft, more new lights required!!
At Akrotiri in a K1, as No5 in a 30 second stream take off at dawn, with a gentle 2 kts headwind, ground roll 8950ft on a 9000ft runway. No lights broken but Safeland barrier damaged. Same pilot as second attempt at Butterworth, but now as a Wing Commander. Seems the air was heated by the precedeing aircraft, as each one in the stream took longer than the one before!! ATC pressed the crash button as they did not think No 5 would make it.
We used to offload fuel at Marham in the summer months, and it was usual to have a large gap, the wrong way, between Stop and Go Speeds at places like Masirah. Ah, those were the days!!
