At the moment, heavies like the E-3A and KC-135 can only be placed on Parking spots 91, 93, 94, 96 and 98.
But as per the aerial image below, they should be able to be placed on any parking spot from 87 up to 98:
Additionally, there are a number of missing parking spots, when comparing to the above REAL LIFE image, they're marked with red circles:
Lastly, parking spots 91 to 98 are currently facing inwards TOWARDS eachother, while they should be facing OUTWARDS like in the first image.
It would be great if ED could spend some fixing these current mistakes to make the map a bit greater!
