Planes are so costly to maintain, insure, and keep in place, renting is pretty much the way to go unless you fly over 500 hours a year. Even then you are lucky to break even. Insurance costs have driven the private aviation market into the same place as a doctors practice. Almost too costly to bother with anymore. Damn shame.  Bill T.

Great video, I'm surprised they had any fuel left to fly back and land. Full afterburners, full throttle, burns hundreds of pounds of fuel almost every few seconds...

I read Richard Bach books about flying from field to field across America back in the day in old biplanes. Very detail oriented, and a great story of sleeping under the wings in a sleeping bag in corn fields in the Midwest.

Wonder if the SR-71 records, (some are still classified), will ever be broken?

Nope, they won't be. There is no need for it with satellites, and a fighter/interceptor that takes a whole state to turn around in? A plane that leaks fuel until G-forces seal the engine? Not a chance. My dad was one of the design engineers on the plane. When he sees the published "records" he smiles and mutters "bullshit". Even after all these years, when the last SR-71 is in the AF museum in Dayton, when asked what the numbers are he still says "classified". You know that bird could move. ;)

Ask your Dad - it was not G-forces and they didn't seal the "engines". It was the heat created by the plane moving through the air at "classified" speeds and the heat sealed the fuel tanks.

Nice shot, Oswald!   ;D

The First one was great," Nothing by Chance", the last of the Barnstormers, a great read for ANY ONE with an interest in aviation.
did you ever read "The Good Shepherd" also by Bach ?

Ain't friction a b!tch?   ;D

I read that the leading edge of the wings on the SR-71 got up to 4,000 degrees from air friction. Then when it lands the pilot has to sit there an hour for it to cool off before he can get out. If they flew from NY to LA they would cross the time zones so fast they would get there two hours before they left. Now that's fast!!!

Dude, I'm a political scientist, not an engineer. All I know is that it leaked like sieve on the runway, but not in the air. My dad could tell you why (in excruciating detail, believe me). Me, I don't care how it worked, just that it worked. If you want to discuss Locke or Marx or what happened in the election of 1896, I'm your guy. If you want to know about jet engines, call someone else. ;)

The Blackbird grew a bit when it heated up. I think it was 3-4" expansion, but it was a long time ago that I heard of it. The heat made everything swell up and quit leaking.

Sorry about the 'hi-jack', Bill......   ;D


The Blackbird crossed the United States in 1990 at a record speed of 2,124 mph.


There are three variations of the Blackbird: the A-12, YF-12, and SR-71.


Blackbird missions over North Vietnam were the fastest ever flown in combat.


At high speeds and altitudes, friction causes the metal skin of the Blackbird to heat up to 400 degrees Fahrenheit.


The pressure suits worn by the crew are identical to those worn by astronauts on space shuttle missions.


The SR-71's engines run on JP7 fuel, which is a special low-volatility fuel. A fleet of modified KC-135Q tankers keep the Blackbird in the air.


The Blackbird's tires are filled with nitrogen and impregnated with powdered aluminum to enable them to withstand heat.


The J58 engines operate as ordinary jets at low speeds, switching to become ramjets at higher speeds above 2,000 m.p.h.


The nose contains reconnaissance sensors. The entire unit is detachable so that different sensor combinations can be quickly fitted.


To withstand the friction-generated heat at Mach 3, over 90 percent of the Blackbird's airframe is made of titanium alloy.


There are four compartments in the fuselage that can house panoramic, long-range and infrared cameras, electronic intelligence sensors and
side-looking radars.


The only other aircraft that approaches the Blackbird's speed is the MiG-25 Foxbat, and it can only sustain Mach 3 for a few minutes, which
is compared to the five to eight hour missions that are regularly flown by the SR-71. The Concorde is the only other aircraft that can
sustain supersonic flight for many hours at a time.


Back when the SR-71 was first introduced, a pilot could set off from one of its three main bases and get photography of any part of the surface of
the earth within a six-hour time period.


The SR-71 is one of the first examples of the use of stealth technology.
