Marvellous aircraft.
The DC6 doesnt come into LHR anymore, it only works ADHOC charters and seldom flies into LHR.
Overhead LHR yes, you are likely to hear that distinctive drone some nights around 2330z as it heads to/from its various cargo activities or positioning to/from CVT.
I bet there are not that many aircraft which can make an GPU jump so high, spin onto its back and burn up!!!!
Those chilling piston sounds at 3am over Derby are enough....
