The Endeavour riding the 747 back home.

I did hear the sonic boom when it landed in the Mojave desert two weeks ago.

Thats pretty cool.

I've always loved the space program, and I've always wanted to see it ride the 747. I remember being in Mexico when it landed at Edwards when i was a kid. It was dusk and you could see it like a shooting star.

It costs the space program some extraordinary amount of money when they have to land in CA. All in transportation costs back to FL.

How do they keep the shuttle from flying away since the air will work its way around its wings as well?

I'm sure they set it up at the proper angle so that the lift generated by the shuttle's wings is slightly less than it's weight. That way it doesn't present much of a burden to the 747 in flight.

The Shuttle has absolutely no lift. The shuttle simply free falls from the sky. They some into the atmosphere at a very very small angle and just use wind resistance to fly in. The same way those new Skydiving suits work, the ones where you can "Fly"



The Shuttle only has one attempt at landing or they will crash. So NASA really doesnt have to worry about lift from the shuttle.

It has to have some lift or else it...
1) would continue in a ballistic trajectory to the ground after reentry (which it doesn't).
2) wouldn't be able to maneuver left and right of track after reentry (which it does).
3) wouldn't need or have control surfaces (which it does).
4) wouldn't need or have 15,000 ft alternate landing sites all over the world (which it does).

any aircraft with no engine has only one attempt.

The shuttle is in effect a glider, but unlike a purpose built glider, can't stay up a long time. More of a "controlled crash"

I went to see the Discovery land on the dry lake at Edwards Air Force base on October 3, 1988. That was the first mission following the Challenger disaster.

While the shuttle certainly has wings and control surfaces, from a laymans point of view it pretty much does just fall out of the sky. The descent angle on approach is impossibly steep, it looks nothing like a commercial aircraft as it heads toward the runway.

What I found most impressive is the sheer speed. We were listening to the radio, which announced when the shuttle was spotted over Hawaii. As I recall, about twenty minutes later it was spotted crossing the California coast. From there I don't think it was five minutes until it was circling over the high desert. The shuttle also makes a very distinctive double sonic boom as it decelerates below the speed of sound.

Oh yeah, it was a great party all night on the dry lake while waiting for the arrival.

Some random specs:

Glide ratio:

Shuttle: Varies from 1:1 at re-entry to 4.5:1 on approach.

Cessna 172: 7.5:1 Interestingly close to the shuttle.

747: 17.7:1

Grob G-102 sail plane: 34:1.

Birdman suit: 2.5:1

I was ticked that it didn't make an overnight stop in Houston. That was the day we had the rare snowfall, so they decided to go up north to Carswell AFB. The day after, they did a low fly by at Intercontinental Airport and at Ellington Field. I would be taking a crappy final exam that day too.

I saw it land at Carswell (now J.R.B. Ft. Worth, or whatever they call it). I pulled into the Wally World parking lot on the edge of the base. Saw a couple hundred people up against the fence, looked south to see it on about 3 mile final aproach.
