Could you find some videos for those cases? Would be interesting to see this in action.
replyConvenient and good infrared video for all these scenarios is hard to come by but would be useful. I think if the DoD was willing to put some money into the budget for practical recreations of UAP scenarios that they then make public, they could do a lot of good. But there'd probably be pushback about wasting money and also risks of leaking information about military sensor capabilities.
replyBut here is a paper showing penguins photographed with a temperature-sensing IR camera, showing the majority of the surface of their body being around -21ºC thanks to the highly insulating plumage.
