I d be surprised That source is three years old at the time of writing this and I haven t heard anything since It would be quite hard to come up with a good sequel to a film like this Scene with the Helicopters I was going to mention the fact that when the three helicopters go down over Scotland the temperatures necessary to freeze it have no noticable effect on the soliders inside they only freeze when they try and get out I am aware that this might be considered original research which is why I havne t included it as of now but I think it is pretty obviously true no ice forms on them and I think if you were in conditions in which your entire chopper was being turned into ice some of it would get on you So what do you guys think
