I don't think the code for a air unit beaming up transport is possible it must land to take in units
maybe you could make it that it 'lands', but looks like its in the air still
i dont know if it could work this way, but its like a jump jet thing, except instead of 'landing', it looks like its still in the air, but its just hovering(like the amphibious transports or robot tanks hover, but much higher), and maybe does a 'beaming up' animation(like the power drain thing), then when it starts moving again it stops,
if you dont understand what im saying just tell me and ill try explaining better, infact, maybe you should tell me what you think i mean, so there's no mistakes, then i can say weather your right or wrong
