Back to the thread and this DC87 take off ::
Someone posted this on AvHerald :
It looks like they entered 01 via Alpha so no intersection departure.
The runway slopes up.
Charlie is 7220 feet forward of the threshold.
From Charlie to Delta, they averaged a speed of 150 kts.
The nose comes up just prior to crossing Delta.
They likely had less than 1000 feet of runway once the main gear lifted off the ground.
As they cast shadow on the localizer, they seem to be about 70 feet AGL.
Do not know if correct but seen worse data with some flex take off.Also the rate of climb afterwards does not suggest important overweight if any..
