This is why the SR-71 Blackbird is the fastest production plane ever

The SR-71 Blackbird is the fastest and highest-flying production aircraft ever to exist. It holds all of the world’s airspeed and altitude records, even after its retirement from the Air Force in the late 1990s.

It’s an incredible accomplishment considering the spy plane was developed during the 1950s and 60s without the help of computers.

The long-range, supersonic Blackbird was capable of flying at Mach 3 for more than an hour unlike its closest competitor, the Russian-made MiG-25 Foxbat, which could do it for a few minutes, according to the TechLaboratories video below.

The SR-71 was only about 45 feet shorter than the Boeing 727 passenger airliner. From nose to tail, the sleek jet measured 107.4 feet long, had a wingspan of 55.6 feet, stood 18.5 feet high and weighed about 140,000 pounds — including a fuel weight of 80,000 pounds.

Remarkably, the Blackbird had better gas mileage traveling at three times the speed of sound than at slower speeds. But it was still extremely expensive to operate, which is why Congress finally decommissioned the bird in 1998.

From its engines to its airframe, this TechLaboratories video explains the incredible engineering magic behind the SR-71 Blackbird:
