Pasir,
Argentine deception techniques made the Black Buck 1 crater appear larger for photo-recce Harrier runs. Simple mud and earth ring on the runway gave the impression that the runway had suffered greater damage.
This crater caused problems with UK forces after the Argentine surrender. RAF News, April 26th 2002, has a piece from retired Air Commodore John Davis. Davis was the first commander of the operations wing at RAF Stanley. In relation to the runway crater from the first Black Buck mission Davis wrote "This rogue crater required a succession of repairs amid what soon became high intensity air operations."
The damage restricted the Argentine air operations and types used. The C-130s continued to use the runway. Other transport types that had been used prior to Black Buck 1, such as the Fokker F.28 Fellowship, were withdrawn from use at Stanley according to the following.
