but if it was flying that high, that fast, wouldnt it freezing on the outside rather than really hot? im only 14 someone explain this to me.

@elite055 Your right that it is extremely cold up at altitude but the faster the airplane flies the more friction builds up on the airplane.

[LiamE69]

@zmatt Its a common misconception that its friction that causes the heat build up. Its actually the compression of the gas that does it.

@LiamE69 Cool do you have an article or something about that, I searched a bit but could not find anything.

Thanks!

"It arrived 4 hours before it took off"

...talk about relativity!

SR-71 's ran on RedBull and pussy on the weekends.

[LIGHTNICK625]

@LiamE69 No, that would happen if the front of the plane was flat (like the heat shield of the re-entry capsules). In fact, the leading role in achieving extremely high temprature outside the aircraft plays the friction of air. Gus compression still exists in the front of the aircraft.

@zmatt Friction doesn't matter much about ambient temperature. You can strike a match in freezing temperatures, in windless conditions.

@gamisooesi only to find out he had already built his own !

[gamisooesi]

They built this plane for Chuck Norris!!!

@elite055

The air running by the aircraft at 3 times the speed of sound created much friction on the skin of the aircraft which caused it to become super heated. Rub your hands together really quickly and notice the how hot your hands get; it's the same principle.

In my dream's I want to be a passenger on the sr-71, looking out onto the earth at 80,000, perhaps I will do that but not in a blackbird.

[mgibilterra]

@elite055 when you are going so fast its creating soo much friction with the air molicules creating heat. but im only 13 so i may be wrong

love the old camera ^_^

in Soviet Russia

Dogs walks you

upps..

Wrong vid

[PanzarMetal]

Any Chuck Norris joke on this one anyone ?
