why does this cone shaped cloud appear when jets hit the sound barrier? :rofl:

its not smoke... its moisture i believe.

its the shape of awesomeness.

The white halo is formed by condensed water droplets which are thought to result from a drop in air pressure around the aircraft.

Got a few minutes? http://en.wikipedia.org/wiki/Speed_of_sound

why would you look on wiki? i would rather listen to people on tst.

sooper serial.

as serious as that hair line. i hope to one day travel at the speed of sound.

lol yea why not just make a thread... all i needed was the word condensation. i dont feel like reading pages of scientific hootinany on wiki


im for theeriuz

It's just an oblique shock wave.

I love wikipedia. I wish it was around when I was in college.

Sound? Pansy, light is where it's at yo! :-p

here's a neat FYI. when you snap a towel it's actually a sonic boom

its actually still debatable apparently.

The only real experiment that was able to accurately prove this possible involved a professional with a bullwhip. It was proven that the bullwhip reach 1400f/s, the speed of sound being 1100f/s.

there was an experiment by some college kids: http://www.hiviz.com/PROJECTS/towel/towel.htm

they "proved" that a towel does break the sound barrier... but they couldn't continuously recreate their findings... so their one success is fairly moot. I also read a response regarding the experiment that they changed to a wet cotten bed sheet to achieve the result and could not with a generic towel

Yes... I used google... ;)

I think this has been posted on here before, but I cant find it.
