[QUOTE="kiwikid, post: 1472580, member: 56094"] Hatrick the temperatures I used are the hunting elevation temperatures. At 35000 ft where the Concord flew the outside temp would be around -50 to -60° C and at the elevation the SR-71 flew it would be a few degrees colder so in actual fact the cone of the SR-71 would have been around 420° C. So if it was 0° C or 32° F the temps in my first post would be relevant for ground temps. [/QUOTE]
