Remarks: 1600px. I just knew that with the right conditions and the only movement at that time, the whale would cause a bit of a stir on rotation. The frost on the sides of the runway was about to settle for the night when this monster rotated.
I think the freezing weather, and the long walk to get to this location was well worth the outcome. Thanks to those who voted :)
Remarks: What an impressive sight ,using most of 23 left "Delta Golf" powers into the crisp Manchester air,with a takeoff weight of approx 550tons and with an unusually good visibility and the pennine hills in the background give a good backdrop as she slightly crabs into the air
