Lockheed SR-71 Blackbird (Part 2)

The SR-71 remained the world's fastest and highest-flying operational manned aircraft throughout its career. From an altitude of 80,000 ft (24 km) it could survey 100,000 square miles per hour (72 square kilometers per second) of the Earth's surface. On 28 July 1976, an SR-71 broke the world record for its class: an absolute speed record of 2,193.1669 mph (3,529.56 km/h), and a US "absolute altitude record" of 85,068.997 feet (25,929 m). Several planes exceeded this altitude in zoom climbs but not in sustained flight.

jerrydoubleu..Most overpressure happens at the moment of Mach1.00-1.30 ,after that overpressure ,increases are very slight, its the intinal first break of air molecules where the greatest overpressure happens, supersonic jets at 100 ft can create pressures of 20-145+BARS but from reading elkranch comments, they are pretty much right-on,hearing the Habu at speed and altitude does sound like distance thunder....J-58 sound frequency at take off, is very different from a sonic overpressure"booming.

In 1974 during the speed run from London to L.A., during the dece start after the timing gates,the, Habu was low enough and fast enough, to blow out some windows in a house in BelAir that Howard Hughes built in the 1930's,then owned by Elvis Presley and sold to ZsaZsa Gabor weeks before the incident, overpressure increases with a decrease in altitude for a given speed.

@fryI78 thanks for info..........going to see one soon!

what was there to 'lock-on' to? by the time it happened

it was long gone.

[fryI78]

Since a "lock-on" was done with radar/infrared sensors and not visualy, no fighter/missile-system would have been able to shoot down the 71, since they came with electronic-counterm. that displayed a "fake" jet a couple of hundred feets BEHIND the real aircraft and the missile would have gone for that...

@elkranch I know that I am not saying anything about that , but fighters have locked on to it but never fired . But then it did not travel at 3,2 all the time

[elkranch]

@Kambanicity The real task for firing on the Habu was keeping the radar lock-on, which on a target traveling at 3.20 Mach was almost impossible....THX

[Kambanicity]

@duplex2411 Yeah but their has been times when interceptros has locked om to it and could have had fireod on it if they whatet to

[duplex2411]

Almost all SR-71 Reconnaissance Aircraft are now in Museums throughout the United States, having flown for 32 years with the distinction of being the "The highest flying and fastest air breathing aircraft in the worldThe SR-71 routinely cruised at Mach 3.2 in continuous afterburner at 80-85,000 feet. The speed and altitude of an SR-71 coupled with superior Defensive electronics has prevented any intended intercept of the Blackbird either by land based missiles or airborne Interceptor threats.

recon what exactly???
