Also i have an idea what
Red would do,what he learned in UCAS

- as a Kid playing Hockey and taking part in snowball fights
when you press snow together it changes the density of the snow, sometimes even makes it to ice.
So anything that made some footprints even if under a new snow would be traceable with the UWB, as it is able to differentiate between density, even more so if they had to transport some cargo away. Only way to avoid it in my book would be not to touch the snow - levitate it all. But when fighters approach a plane they would never want to be at a mercy of a levitate spell so i guess there should be at least some tracks to follow.
So my Question to GM. Could red Get those differences on his UWB? what test would that be? and if by any means they have hidden their tracks, i will tell you why that would not work.
