Can infantry ever dismount from airborne WiGE vehicles?
The mounting rules on Total Warfare page 224 are very clear, stating that either the WiGE (or VTOL) vehicle must be landed, or the infantry must have VTOL MP and be at the same elevation in the same hex as the WiGE/VTOL. However, the Dismounting heading starting on the same page and continuing onto page 225 never explicitly states that the vehicle must be on the ground, and there is no further mention of WiGE vehicles under that heading.
The existence of special rules for dismounting from airborne VTOLs implies that dismounting from an airborne ground unit is a special case, and WiGE vehicles are specifically not mentioned under that heading, so I expect the answer is "No," but I have someone trying to argue this and would like an explicit ruling.
