Ever seen a sonic boom?

Ever seen a sonic boom? A NASA website has daily pictures from a variety of astronomical sources. Today's is a little more down-to-earth; the visual representation of a sonic boom, captured when an F/A-18 Hornet crossed the sound barrier.

That's pretty interesting. I used to go out to the beach near the airport with my dad in the summer and watch concords take off, but I'd never actually seen the sonic boom.

Here is a link to an mpeg of a jet breaking the sound barrier during a low altitude flyby of an aircraft carrier.
File is about 1.4MB. Via jimwich.

Wait a minute, I know I've seen this photo before. I know sometimes the APotD is from the archives, but surely they wouldn't reuse one...?

That pic turned up last year (I wonder why APOD is just getting around to it now). There was considerable debate about its validity, mostly dispelled by the provenance. A lot of self-styled aerospace experts were certain it had been doctored!

Heh. Simulpost there. Anil, it was widely distributed (newsgroups, e-mail) and definitely blogged several places. It's from a .mil site originally, not NASA, which probably accounts for the delay.

Here is an account of how the photo was taken. Explains the cloud phenomenon and the photographic technique. Also from the jimwich archives (Dec. 2000).

apod reuses pictures from time to time, especially when it's related to some sort of anniversary date or something. it's been my home page for a long long time and I've seen several repeats.
