Question

How fast could the fastest jet go around the world?

Answer 1

B-70 would have made the trip faster than the SR-71 fewer mid air refueling stops, every two and half hours instead of every hour and a half. less fuel leakage also

Answer 2

NasaS blackbird would run out of fuel 2 times so counting stops about 17 hours with the jet stream

Answer 3

Sorry Phillip, the XB70 was no where near as fast as the SR71.

As printed in an Air Force Now magazine in the 80's, the SR71 could beat a 30.06 bullet in a flight if the speed of the bullet could be maintained.

Also quoted in the article, the SR-71 flies so fast that it actually creates a vacuum in front of the aircraft that pulls it along. The wing leading edges glow white hot.

The engine was tested running off the exhaust of another jet engine. It was glowing red in the photos.

The actual speed and altitude of the aircraft have never been  published. That says something for 50's/60's technology, and when you have an open pocketbook.

Viva Kelly Johnson! P38, F-104...

Answer 4

The Fastest Jet in the world is probably the SR-71

In July of 1976 the SR-71A sets speed and altitude records

Altitude in Horizontal Flight: 85,068.997 ft.

Speed Over a Straight Course: 2,193.167 mph

Now - that's FAST!

The earth's circumference is 24901.55 miles ...

So, approximately 11 hours to make it around the world.

Answer 5

Well, theres this Jet that NASA uses for reseach called the

C-77 Blackbird.

An estimation would take it is about 15 1/2 Hours

Answer 6

prob B-2 bomber empty...you dont get shot down over enemy territory....cant see you lol and they have great range without refueling so less time doing 250-300 knts trying to plug into a KC-135.

Answer 7

bout 18 hours, that is if it's running on jet fuel

Answer 8

NASA's X-43 Hyper-X experimental aircraft is an unmanned vehicle and has been clocked at speeds ranging from Mach 7 to Mach 10.



At the X-43's cruising altitude of 100,000 ft, these Mach numbers correspond to speeds of approximately 4,750 mph  to 6,750 mph.
