Can you imagine how smart the people who engineered this were?

 

The faster it goes, the more efficient it gets. The Soviets made Mig-31, which was an incredible airplane, but they had to run on the after burner and the engines melted. Yet SR-71 could cruise at Mach 3 like nothing.

This kind of shit is so cool. 

I just took a class on aircraft systems and part of it was a tour of a local air museum. Each plane has some ridiculous feature that is specific to that plane. Each design is unique and has a story. There is so much cool shit with military aircraft.

The SR-71 is something special though.

Nah, there is no need nowadays. They just use satellites.

The concept is incredibly effective. The biggest downfall of the SR71 is it became obsolete with modern satellites.

It also leaks like a motherfucker. The skin contracts at speed due to the pressure and heat and retracts on the ground and pisses fuel and hydraulic fluids like crazy.

The dad of a girl I used to date flew it.  I love military aviation, and would get a boner listening to him tell stories. His daughter giving me a handy under the table may have been a contributing factor as well.

I lived on Okinawa in the mid 70's. They had 2 stationed there.  We would see them flying overhead during school. Was quite an awesome sight!

They have one at the local AFB museum, still my favorite one to see. It was a big deal when they unveiled it here years ago

That's funny, I was born on Okinawa in the mid 70s.

Some markings weren't paint they were chalk. Paint would melt. You could see through the engines at max speeds.

Brian Shul tells some cool stories. Here's one lecture he gave, my fav.

Great thread. Some things about the SR-71 are still classified.

Wonder if you took our military from thirty or forty years ago (these, I imagine A10's, etc) how they'd do against Russia or China today. Like how far back would you have to go with our military to lose to modern day Russia or China?

Military equipment usually lasts for a very, very long. This is not an iPhone that gets refreshed every year.

Even the old generation F-16, etc. will be relevant in 50 years.

I honestly believe we have spaceships now.. all these sightings aren't "ALIENS", it's our military super secret developments. This plane is amazing and all, but I'm sure our current technology is way ahead of this SR71. We don't see tech till it's 20-30 years old..
