“It Can’t Fire a Gun and Doesn’t Carry a Bomb.” That Was the Air Force Chief of Staff on the SR-71 Blackbird, an Aircraft With 17,300 Sorties and Zero Losses to Enemy Fire.

Across its life the SR-71 Blackbird program flew 53,490 hours over 17,300 sorties, including 11,675 hours above Mach 3 — a record of production...

At 75,000 Feet an SR-71 Blackbird Pilot Could See the Horizon 335 Miles Away and Make Out the Curvature of the Earth. He Could Also See the Contrail of the Soviet Fighter Coming for Him, 100 Miles Out.

The SR-71 Blackbird was outside Soviet territorial waters, but the interceptor knew where the turn was coming. Ed Yeilding assumed the MiG pilot had...

A US Air Force Mach 3 SR-71 Blackbird Flew More Than 15,000 Miles in 10 Hours and 30 Minutes With 5 Aerial Refueling. The Limit Was Not Fuel, Not the Engines, and Not the Crew. It Was 212 Liters of Liquid Nitrogen.

The SR-71 Blackbird carried two consumables that each capped the mission. Liquid nitrogen in Dewar flasks in the nose wheel well, and triethylborane —...

Lockheed SR-71 Blackbird Came Back From Every Mission 3 to 4 Inches Longer Than It Took Off. At Mach 3.2 the Titanium Skin Ran Around 620 Degrees Fahrenheit, So Lockheed Built the Panels Loose on Purpose and the Fuel Tanks Leaked on the Ramp Until Heat Swelled the Joints Shut.

For the SR-71 Blackbird, Corning spent years and millions developing solid quartz windows because ordinary glass would have distorted. The wing skin was deliberately...

Over 4,000 Missiles Failed to Hit a Single US Air Force Mach 3.2 SR-71 Blackbird. Speed Was the Only Way to Survive as It Had No Weapons to Fire Back

The SR-71 Blackbird did not dodge missiles so much as it made the intercept mathematically unaffordable, arriving and departing faster than the defense could...

The Mach 3 US Air Force SR-71 Blackbird Ran on a Fuel So Stable You Could Put Out a Match in It. Then They Had to Invent a Way to Light It.

No tanker on earth could carry JP-7, so the Air Force built one for the SR-71 Blackbird. The KC-135Q had isolated tanks and separate...

To Fly the US Air Force SR-71 Blackbird at Mach 3 and 85,000 Feet You Needed an Astronaut’s Body, Iron Nerves, and the Stomach to Outrun Soviet Missiles

The Air Force never advertised. A board met at Beale roughly every six months to fill seats opening seven to nine months later, working...

America Did Not Have Enough High-Grade Titanium to Build the SR-71 Blackbird, So the CIA Bought It From the Soviet Union Through Shell Companies in Neutral Countries. The Airframe Was 85 to 90 Percent Titanium, and Much of the Ore Came Out of Soviet Ukraine.

Cadmium-plated steel tools embrittled titanium on contact, so Lockheed had to build new tools out of titanium for the SR-71 Blackbird. Parts washed in...

Lockheed SR-71 Blackbird’s Pratt & Whitney J58 Engines Ran at Full Afterburner for Hours at a Time With Exhaust Temperatures Near 3,400 Degrees. At Mach 3.2 Cruise, Roughly 80 Percent of the Thrust Came From the Inlet, Not the Engine.

The J58 burned JP-7, a blend so hard to ignite that a lit match dropped into it goes out. Starting the engines required a...

Congress Spent $100,000,000 Bringing Just 2 SR-71 Blackbirds Back from Retirement in 1995 and Another $30,000,000 in 1997. By 1998 the Program Was Dead Again.

Across its whole service life the SR-71 Blackbird accumulated 53,490 flight hours, 11,675 of them above Mach 3, over 17,300 sorties. By the late...
