I just saw an excerpt while trying to find out how many miles 70,000 ft. was( a little more than 13 miles) and the service ceiling is 84,000 ft.

That is high.

If it went into "space" by mistake, could it come back?


It couldn't make it to space, it does not have enough power to do so. But if it hypothetically did its' engines would not work, as there is no air for the jet engine to breath. But it would be able to eventually come back down due to orbital decay, although it would burn up in the atmosphere, as it is not adequately shielded for re-entry.

Thanks for the awesome clip zorgon!

I am into skydiving and all I could imagine was jumping out of that plane at 70 000 ft, let alone 30 000 ft higher than that.

103 000 feet skydive.

Cool thanks for the lesson!

and @zorgon I wanna come on a Pegasus field trip !

This one seemed too fast for a Pegasus. I am not sure what the Pegasus is capable of, but this just seemed too high and fast. 3 loud booms hitting you in the chest and the next thing you know, this thing is gone!



As for October, I don't think I will be able to get out much. I may not have any free time until about November.

That is not entirely true. If it did accidentally break from the atmosphere, it could re-enter without burning up. Its speed would not create the heat a space shuttle or satellite would. The friction from re-entry would be no different than the friction from flight.

However, it would most certainly crash! Without the dynamic support of the atmosphere on the vertical stabilizer and wings, it would begin to tumble or spin. Once it started a descent back into the atmosphere it would tear apart! I can't remember which test pilot's have experienced this, but it has happened.

getready,

Except....barring a Star Trek tractor beam or something, the U-2 just will not be able to EVER leave the atmosphere, no matter how tenuous.

The term "coffin corner" comes to mind. More technical term, "Flight Envelope".

Notice, in the video...which you know, the airspeed is actually quite low, I saw it at about 132K. AT its service ceiling, it has about a 2-3 knot margin, between 'overspeed' for that altitude, and stalling.

Fragile as the wing is, I'd hate to see either events, and the structural damage resulting...
