on 1rst video nuke reacts with aeon TMD.
Edit: afaik all nukes not just can collide with TMD thingy that aeon TMD spits out, but also get attacted to it, even t4 nuke does
i don't know what the point of testing collisions with air in supcom 1. afaik if nuke collides with unit it will explode no matter what, that will only help against projectiles that can damage nuke.
so this does not happen anymore : https://www.youtube.com/watch?v=5tuLUyKMWik
