I'm a history nut, and I don't apologize for being that way.  I love reading up on history and learning from the past. Here's a story I came across a few days ago on Wikipedia.  The FAA prohibits planes from breaking the sound barrier over land.  But before they made this rule official, they had to do some test.  These tests resulted in the Operation Bongo II in which 1,253 sonic booms were carried out over the OKC skies from February through July of 1964.

 

Starting on February 3, 1964, the first sonic booms began, eight booms per day that began at 7 a.m. and ended in the afternoon. The noise was limited to 1.0 to 1.5 pound-force per square foot (48 to 72 pascal) for the first twelve weeks, then increased to 1.5 to 2.0 psf (72 to 96 pascal) for the final fourteen weeks. This range was about equal to that expected from an SST. Though eight booms per day were harsh, the peak overpressures of 2.0 psf were an order of magnitude lower than that needed to shatter glass, and are considered marginally irritating according to published standards. The Air Force used F-104 and B-58 aircraft, with the occasional F-101 and F-106.

 

I love airplanes, and I love Oklahoma.  Just wished I lived back in 1964 to have been a part of this unique history.

Here's a video of an F-18 breaking the sound barrier.
