Nice find Bob. Thanks for sharing.

Thanks for a VERY cool physics lesson! This one my grand daughter really enjoyed.
Regards.

Back in the late 50's early 60's B-58's used to rattle the windows in Indianpolis. I thought it was pretty cool. But the Air Force got harrassed away for civilization and when I got in we could only bust mach in remote desert areas.
It appears we've come full circle and people think supersonic cool again.
It always impresses me that Chuck Yeager did it for the first time in 1948 and only twenty years later students were doing it six months into training.

Awesome! Thanks Bob!

What I think is more impressive, is that in 1938, almost all of our front line fighter aircraft were fabric covered and wire braced biplanes. And in just ten short years, we evolved into the X-1 and the speed of sound was broken. So much technology was discovered and advanced over that time period. Very similar today in my opinion and one of the problems with the economy. So much technology has been developed so fast in the last ten years, that there is no time for anything to get a foot hold and an industry and jobs to be built around it before the next greatest thing comes around. Everything and everybody moving so fast!! Almost at the speed of sound!

. . . Chuck Yeager did it for the first time in 1948 . . .
1947, actually. October 14th.

Here's another physics lesson ;) : http://www.youtube.com/watch?v=CAG6H9M6gZo - shows the sort of damage that a sonic boom can do. (NB there's a bit of language at 0:18 - 0:22 that some might want to mute out, particularly if you're going to show it to your kids..)

I've seen quite a strong case made that George Welch actually did it 2 weeks earlier, in the XP-86. It makes for interesting reading, if you look into it.
-
I think there is also an argument that Slick Goodlin did it in the X-1 before Yeager did, and that is why he started his hold out for more money, or something like that. Might depend on who's book you read.
Type at you later,

if George Welch did break it first, since there were no official FAI observers or monitoring equipment present, it just remains as a great story and nothing official.

WOW THAT IS AMAZING!!!

WOW THAT IS AMAZING!!!
Perhaps :! n~ a new age in R&D will soom be approaching that will to finally get "A HANDLE" on the sonic boom that is produced when exceeding the speed of sound.... H^^
