5 miles is a standard vortex gap between Heavy and Medium.
I take your word as gospel point5, but today with said AN124 it really did seem as though the time gap was pretty long in comparison with other heavies such as 747,340,777,330 et al. Was this because of the 'blunt' shape of the Antonov and the amount of air that it shovels out of the sky in comparison to it's more elegant western civvy aircraft ?
Also did it park on 701 to facilitate the installation of the A380 model by road rather than park up in the cargo area ? I had imagined that 'they' (who?) would truck it over 27R after midnight and pass it through the emergency gates to the roundabout plinth.
