If anyone lives in the LAX area, the shuttle is due down in about a hour. From what NASA is saying, the sonic boom should be able to be heard around the Los Angeles area. They have been cleared for the deorbit burn down into Edwards AFB. (The 747 that hauls the shuttle will be put into use).

...Lived in LA-area (Orange Co.) for years, always got a kick out of hearing the "double-thump" when the shuttle passed overhead.

That's one of the (few) things I miss about living out there.

Although on 112 degree summer days, I sometimes wonder...

Do you think it will be able to be heard as far south as San Diego County?? How loud will it be in L.A. (as loud as a jet at FL350? etc..)
Thanks

I don't think it will be at FL350 as it passes over LA. I'm not exactly sure what area of LA its passing over, check out spaceflight.nasa.gov and find the groundtrack, its the first Edwards landing for today. This is the first time in 4 years that it will be landing in Edwards, the last time it did that, I saw it.

Scuttler - it isn't often the shuttle lands at Edwards...there was talk today if KSC couldn't be used, and Edwards couldn't be used either, White Sands in New Mexico would be activated. That can be considered a emergency situation since the shuttle cannot stay up longer then tomorrow. The sound of the shuttle in the LA area is the sonic boom. Otherwise, it would just be a dot in sky.

I used to live at Daytona Beach when I was student in Embry Riddle I heard the sonic booms couple of times in different flights of the shuttle but ı was living in a very quiet neighbourhood(no cars,planes etc.around)I've never been there but I think LA is a big city and noise around can be a problem to hear the sonic booms especially around the downtown areas.Its very hard to hear the booms if its not quiet around

Doesn't the US have a law about winged object flying over land at more than the speed of sound. I mean, if the Concorde can't do it, what gives the space shuttle the right? :?

I heard two sonic booms at exactly 1354 PDT and that was really neat to know that the Space Shuttle was on approach to Edwards!!!The777Man


Need a Boeing 777 Firing Order....Further to fly....CI, MU, LX and LH 777s

When I lived in OC, it was back before they started landing the shuttle at KSC, so plenty of opportunities to hear it as it passed overhead.

And yes, I suppose that if I had seen it, it wold've been a mere dot... but by the time the sonic booms got to me, the bird was probably past the effective horizon, with ground clutter, anyway. In any event, although I would listen to Mission Control on the JPL 2m repeater (they still do that?), I never sat outside and looked for it as it approached, being in those days a lazy person.

And as for the laws regarding sonic booms, I just don't know, but I'd bet that NASA can get any kind of waiver it wants. I'd vote for it, anyway.

One advantage of it landing at Edwards: some lucky folks will get the chance to see it on top of the 747 for the trip back; very early in the shuttle program, I saw it on the ground during an overnight stop at Bergstrom AFB (now AUS / Bergstrom Internaional Airport), and it did a very impressive, fairly low-altitude fly around over Austin before landing; good PR at the time, and a real kick for this ol' boy.

The777Man,
The governement can do what ever they want. If they want the Space Shuttle to fly over land, then it will happen. Commercial flights can not fly supersonic over land.

I used to live in Pasadena, Ca. (15 miles NE of L.A.), and I remember hearing the sonic boom as it approached Edwards Air Force Base 35 miles north.
I heard it in P.E. when I was in 7th grade back in 1985. I thaught it was cool!
I wish the Concord could fly out of SFO. Planes pass over my place at about 5,000 ft. and I'd love to see and hear the Concord fly over!



Bring back the Concorde

Yeah,
I also saw and heard the Shuttle Twice here. I live near Biloxi, MS and I heard John Glens Shuttle boom by, but I didn't see it. Then in Summer 1999, I watched and heard the Shuttle coming home. They were headed to the Cape, and we are on the flight path   I also get NASA TV, so I got tracking.

As a Californian it's nice to hear that the shuttle is landing in SoCal again. Some day I've got to get up there to watch it come in -- but since Edwards is now an alternate landing site I probably wouldn't know about it far enough in advance to get up to EAFB.

Besides KSC, EAFB, and White Sands, what are other alternate landing sites? I once read somewhere that the Reef Runway (aka 8R) at Honolulu International Airport is one. Any others?

Anyone know specifics of the shuttle's descent rate? Ten minutes before touchdown: how high, how fast, how far from Edwards? Same questions for five minutes. How far are they from Edwards when they reach airliner cruise levels? "United 2044, amend your clearance, climb maintain FL250, uh, make that 210, no, let's try 180..."

I read somewhere a while ago the runway at Easter Island Airport was to be extended to be used as an emergency landing site for the shuttle. I would imagine they also have a few sites around the world in case of dire emergency.

There are alternate landing sites according to the type of emergency as well as the location of the shuttle. You can find this information at: http://spaceflight.nasa.gov/shuttle/

For example, if the shuttle needs to abort orbit just after takeoff, it can land in western Africa.

A twist to this discussion: According to the aforementioned web page, there is also an alternate LAUNCH site! If the shuttle were to be launched into a polar orbit (that is, orbiting pole-to-pole rather than parallel to the equator), it would be launched from Vandenberg AFB, also in So Cal.

For anything you ever wanted to know about the shuttle-including approach charts specifically for the Shuttle in to KSC, White Sands, and Edwards, "The Space Shuttle Operator's Manual" It's a very good book that wll answer all these questions-this is NOT an advert-just a source of info for people to use.

Shuttle descent rates vary but 30 mins before landing the shuttle commences re-entry and once in re-entry is over-the descent rate seems to be around 15,000 ft/min.-Imagine trying to land a 747 at that rate!!

Also, right before touchdown from 14 seconds before to touchdown, the book says that the shuttle goes from 330 mph to 215 within a space of 10 seconds-and the landing gear drops at that time also. That's a heck of a final approach deceleration!!
