What you're hearing is Neil Armstrong and Buzz Aldrin in the cramped cabin of their

bizarre-looking spacecraft Eagle during the final three minutes of their descent to the

moon. They're standing up as they fly and both of them peer through small, triangular

windows in front of them as they work the controls. Buzz Aldrin is calling out the

altitudes and rates of descent as they approach the lunar surface. Here they're just

750 feet above it. Now they're at 600 feet, about 200 meters from the surface. You may have

heard Neil Armstrong say pretty rocky area. He's talking about the landing site they're

currently headed toward and it's not what they were expecting. It's listed with large boulders

and it's certainly not a safe area to try and touch down. And so, to avoid potential disaster,

he changes course and flies Eagle over the treacherous expanse of rocks by slowing his descent rate

and instead he's now moving forwards at speed. He's improvising.

A Apollo 11 flight director, Gene Krants, recalled the drama.

Armstrong has to pick out a landing site and he's very close to the surface and instead of

moving slowly horizontally, he's moving very rapidly. I mean we've never seen anybody flying

at this way in training. To add to the tension, Eagle is close to running out of fuel.

During all this, the spidery-looking spacecraft twinkles in the brilliant sunlight.

It has the appearance of something half finished, half realized. It's flimsy and strange.

It looks like nothing on earth. Because of course, it was never meant for the earth.

We choose to go to the moon. Cap time, we're go for landing.

Eagle gives a year of go for landing, but we're getting on the 12th floor through the

program alarm. Holded at 18 foot, we're going to make it a thing.

Roger, go, level. 60. 60 seconds. We've had chest down. We've gotten me a down Eagle.
