...the limiting factor in the speed of the SR-71 was what was known as CIT -- Compressor Inlet Temperature. The maximum allowable CIT was 427 degrees Centigrade. Above that temperature, the engines would begin to burn up. On a "standard day" (temperature wise), the outside air temperature at the SR-71's operating altitudes would be minus 56 degrees Centigrade. On one of those "standard temperature" days, the CIT would reach the limiting 427 degrees as the aircraft was accelerated to Mach 3.2. If the outside air temperature was warmer than standard (say minus 52 degrees), the CIT would reach 427 degrees prior to reaching Mach 3.2. Conversely, if the outside air were colder than standard (say minus 60 degrees), the 427-degree CIT would be reached at a higher Mach number. There were occasions, especially when flying out of Okinawa, where the outside air temperature was considerably warmer than standard. If it was warm enough, missions might have to be aborted due to fuel considerations. The airplane was not as fuel efficient in warm air as it was in cold air.
Gil remembers one mission flown over the Barents and Arctic Seas when the outside air temperature was showing minus 90 degrees Centigrade, or 34 degrees colder than standard. Due to that extremely cold air, the airplane reached 90,000 feet and the slowest speed he could maintain was 3.15 Mach. Turn starting points and bank angles had to be manually adjusted to avoid getting too close to the Soviet Union's land mass. When they rendezvoused with the tankers for their next in-flight refueling, they had 12,000 pounds (nearly 2,000 gallons) more fuel on board than the flight plan called for. Those J-58 engines loved cold air.

@Tankace1 Well, that's your problem right there :)
Im on mobile @SledDriver
@Tankace1 You mean 10,000 mph? XML modding makes it easy.
Wow my best build cant even hit 10000 @SledDriver edit: i also never posted mine because an update broke it and i dont know how to fix it
@Tankace1 I've never posted my fastest build. It has no top speed, it just keeps accelerating. I've taken it to well over one million mph.
Does anyone here actually know what sleddrivers fastest build is?
@Shemes213 You asked a civil question, no need to apologise.
Oh sorry I didn’t realise @SledDriver
@Randomdoggo k
@Nickr I know, right? Just an endless stream of people who don't think for themselves, who don't care to talk to me to see where I'm coming from, who just regurgitate whatever propaganda they've heard from the haters on this website and who feel free to offer me advice when my building skill is many, many levels above theirs. Oof indeed.
@Randomdoggo If I want your suggestions, I'll ask for them. But for your information, I build landing gear when I feel like it. I'm fairly sure that mine is the only XB-70 on SP so far to have landing gear with the three-axis rotation of the original. Which is not a tremendous achievement by my standards, but considering no one else has done it, I find it amusing that people think I can't build landing gear... especially when I've addressed the matter in the FAQ section on my profile.
@SledDriver oof
@Maxwing1 Were you nice? Did you upvote my build? Did you leave a nice comment? You really couldn't find one positive thing to say about a build like this? No, instead you had the nerve to ask why I don't just do the same thing as everyone else. Considering all that, I think I was a lot nicer than you deserve.
You Could Be Nicer About It @SledDriver
@SledDriver de rien mon cher ami ;)
@Nerfaddict Good.
@SledDriver ok
@Nerfaddict Correction: I am not an average person.
@Maxwing1 What's a "normal" plane? Who gets to define what's "normal"? And where does this idea come from that everyone should only do what someone has decreed is "normal"?
If everyone only did what's "normal" we'd still be living in caves. Because that was "normal" at one time.
You look at something that's several levels up from "normal", and instead of saying "wow, that's amazing" all you can say is "why don't you make normal planes"?
I hope you change your attitude radically sometime soon, or you're headed for a dead average life.
@FOXLOVER It's not available.
@Maxwing1 he is not a normal person
Why Don’t You Make Normal Planes? @SledDriver
Where can I download the script an how to use it please?@SledDriver
Glad you find it so, @Tang0five
Interesting bit of info there!
