smurph :

the engineering boggles the mind. there was no computer design back then

scottvice225 :

When I get hot, I grow 6” too…. Not impressed.

brezbone :

image what they have now...

Bright Noa :

They have one at the kansas cosmosphere suspended in the air inside the building. Really neat. I remember the guide telling me it leaked fuel until it would expand and stop leaking

itsRick27 :

1960's Skunk Works = smartest people on the planet

StupidMetalWiddler :

I work for the company that designed and built that engine! I have my own tooling department and do tons of R&D work for them!

NoneOfYourBusiness :

Designed with slide rules, kids. If you don’t know what they are look them up. No computers.

Rob :

I laugh when people say the space shuttle is advanced piece of aerospace engineering. No way. The SR 71 is far more advanced. And yes, I am an engineer and I used to work at NASA.

Rory :

Brilliant Engineering... All with immense creativity and a sliderule... American ingenuity at its best.

The Way :

Proof the earth is flat

JadedSoul :

they designed this with pencil, paper and unassisted math homework.. the story of this aircraft is one of the most incredible things humanity has ever done

Paul Pryor :

ok...so...3.2 is optimal ...not maximum....usually max is 15 to 25% more ??????

GRFFGR :

My dad was the 2nd shift General Forman of Experimental Dept in East Hartford Ct. He help design and get into production the first Engines. He worked there 36 yrs. Love ya dad.

dkev :

Pratt & Whitney, Dependable Engines

Lumin8rJay :

Imagine it was all done on a slide rule… these engineers were absolutely brilliant

biggacarbzq :

Any guy knows how expansion works in a high friction environment

Stud Muffin :

The most amazing aircraft EVER produced!!

Frady :

To me this is the peak of human engineering

broadsword27339 :

I believe it went faster

brett weppelman :

How do you test it?

keithvantassel972 :

It was the Aerostar program

Slayer6 Yup :

That’s why it leaked fuel like a sieve on the runway. The tanks expanded and sealed in flight

Nope :

Jess Finnegan :

Explain how the space shuttle went to escape velocity if 80,000 ft was 2300 mph 😂
