I see a Polet An124 routed KAFW-CYQX-EGLL & arrived at Heathrow early this morning, flightplan gave RA82010 as the reg'.
It then departed at around 1225 as POT1039 to LIPZ.
How did ATC plan its departure as when i've seen them depart East Midlands, they usually have to sit on the runway about 5-7mins for the engines to heat to the correct temperature. I'm guessing this would severly disrupt the departures at Heathrow.
