Boss is here on holiday -
ACSA used to use D1 as a parking overflow area but that taxiway is used to gain access to the SAPS hangars. D3/4 are now used for the overflow, the main advantage is that the a/c can either be towed over there, or taxied there and it has 2 access routes, so easier to use. It still allows us to move a/c around and by parking them on D3/4 they do not get in the way
