2,200 mph/4200 k/h or so

Top speed ever was about 4,078 mph in a steep dive.

It should be noted that this recon jet has been decommissioned for some time now.

About 3 times the speed of sound. (3 mach)

An SR-71 uses Jet Propellant Number 7, or JP-7. The exact composition of this stuff is still secret.

It was developed in the early 1960's and accepted into service in 1966.

The SR 71 was created between 1960 and 1963 and first served in the USAF in 1964

no. it's top speed was calculated to only be mach 3.5

Record height is 85,000 feet above sea level.

At full speed 11.5 hours plus refueling time.

The SR-71 was built as a military stealth reconnaissance plane that was faster and more agile than the current military rockets, bullets, and even ground-to-air missiles of the time it was developed.

From the beginning of development, the Blackbird was intended to take the place of the Lockheed U-2 Dragon Lady for all recon roles. It was based on the existing XB-70 Valkyrie bomber frame and power plant, and vaguely resembles it.

its still classified - the USAF/NASA will only admit to 2,193.17 mph; 3,529.56 km/h but every time some new plane challenged the record, they just sent up an official mission to beat the standing record at the time. Nothing ever beat it.

An SR-71 flies at the speed of more than Mach 3.5.

2 hours

A plum starts out as a single seed in the center of the protective plum fruit. After germination the tree will grow to about 3 feet in the first year. It will start producing fruit in 5 to 10 years depending on the variety and growing conditions.

2 hours.

Planes are considered girls.

Indeed, many pilots (especially military ones) call their planes "she", they grow attached to them, they love them, they take care of them, they dance together in the sky, they also like to show them off (e.g. Vichy French pilots showing off their planes to ladies in 1940 North Africa)

An old veteran pilot always loves to see the old girl he flew with, this is because many pilots (especially of famous planes like the Spitfire) form such a strong bond with their planes they never forget the bond they share, it's a life-long love.

Mach 3 = 2283.6211 mph

Mach 3.3 is about 2,512 mph depending on altitude.
