How fast is a jet plane? |
[Edit] |
Additional Information
Fighter jet aircraft fly at speeds in the low mach numbers. Mach one is roughly 750 miles per hour, give or take, and military jets can fly at well over a thousand miles per hour. Back in the day (July of 1976), the SR-71 set the jet speed record. Radar clocked the thing at 2242 mph. Oh, and the record still stands. This highly sensitive aircraft project probably holds back data that would top this figure, but the information won't be coming out soon if it exists. You want raw speed? The Blackbird is the answer to your prayers. Use the link and read about this amazing aircraft. The pics alone are worth the trip over to our friends at Wikipedia. As a caveat, there is a much faster jet called a scram jet, but it is unmanned. The NASA X-43A can hit Mach 9.6 which is about 7300 miles per hour. An Aussie scram jet hit Mach 10 (about 7600 mph), but it was upon re-entry after a test run, so it's kinda like gravity aided.
