Question For Those That Have Heard Sonic Booms

Mon Oct 23, 2006 11:09 am

I'm going to the EDW AFB open house this coming weekend, and my main reason to attend is because a few of the planes are supposed to go supersonic (at least they supposedly did last year). Although they do it way up at the flight levels. I've never heard a sonic boom, my roomate said he heard the space shuttle once, and that it was really no big deal, just a loud, uhm, boom boom. lol

We discussed supersonic flight in my aerodynamics class, so I understand the effect for the most part, but if anybody still has an uncontrollable urge to explain it, go ahead. Big grin

So what should I expect? Should I cover my ears? Will it be worth the 7 hour drive out there?

Thx  wave

It sounds just like a clap of thunder. If your going just for the sonic boom, stay home and wait for your next thunderstorm. If your going for the show... enjoy

If they're gonna do it up high, then EMBQA is correct - it won't be much. Here in Florida, I've heard the shuttle many times and it is just a "boom, boom." Nice way of announcing that the TV coverage will start in a few moments, but otherwise not much.

Now, if they do it down low - then you MUST go. I've been fortunate to see F-14s do the "Need for Speed" pass from a carrier (not the same as the show on land) and the BOOM gets you in the chest! Very impressive! (Well, that and the A-6s doing the "Wall of Water"...

The problem is that down low, they're likely to break windows and such - they'll certainly set off car alarms and frighten the bejesus out of anybody not prepared.

These videos may be better that what you'll hear at the show, just turn up the volume:

They did do this on Saturday last year. They DIDN'T do it on Sunday, which was the day I went to the show. I'm still quite bitter about that....

But the show was awesome anyway, so I'd recommend going.

It is as other have said just like a long rumbling clap of thunder, I could virtually set my watch by the time I would hear it each night as Concord went off over the Atlantic, and it sounded the same every single night.

Interesting where we used to live, the lounge had a fairly lose ceiling made from toung and grove boarding, as the sonic boom reached us they would all jump and rattle in waves up and down the length of the ceiling. It is a shame I don't hear it any more.

I remember hearing them every now and then in the mid-1960's while growing up in western Wisconsin. The scariest one was when a Navy pilot buzzed my town in 1967.

The last time I heard one (actually a pair of them) was right after 9/11. A pair of F-16's were en route from Duluth, MN to intercept an airliner over Iowa. A passenger freaked out and rushed the cockpit of an airliner en route to ORD.

yeah, although the last time I heard the shuttle come back, it was like that also...went straight through my chest. Must have been lower or something.

Last year in Tampa, an F16 or two apparently went supersonic to or from MacDill. I'm assuming it was a similar incident (airliner intercept), but nobody really knew. Many windows actually smashed in the vicinity! It was big local news for a day or two  Smile

If it happens right overhead at high altitude (and it will be at high altitude), then you will hear two sharp bangs separated by a few milliseconds - like someone fired two rifles almost syncronously a few feet away.

If you hear it at some horizontal distance it will be more like rumbling thunder.

I have heard it overhead only once. That was in deserted Norwegian mountains where it was so quiet that I could hear a bee 30 feet away. Then suddenly "those rifles fired" with no warning at all, followed by ordinary jet sound.

First I jumped ten feet high, then I looked into the sky and saw a Northrop F-5A at something like 15,000 feet.
