Boom goes supersonic

A few weeks ago I went to Mojave to witness the first supersonic flight test of the Boom XB-1 experimental plane. The flight made history by breaking the sound barrier three times, reaching a top speed of a bit over Mach 1.1. It is the first privately developed aircraft to break the sound barrier, and the first civilian aircraft to go supersonic over the continental US.

Even more amazing, afterwards, Boom announced that with the right engineering, a sonic boom can refract in the atmosphere and never reach the ground. A boomless Boom! This could enable supersonic flight over the US with only a minor regulatory change. (@bscholl)

Here’s a pic I took of XB-1 getting ready for its historic flight:

See here for a few videos, as well.

Some posts and thread from Blake, both before and after the event:

News coverage:

Some papers weren’t interested: “We offered pre brief interviews to both WSJ and NYT and invited both to come watch the flight. WSJ said supersonic isn’t newsworthy until the full-scale Overture is carrying passengers” (@bscholl). Which reminded me of this bit from David McCullough’s The Wright Brothers:

Writing his autobiography later, James Cox, publisher of the Dayton Daily News, remembered reports coming “to our office that the airship had been in the air over the Huffman Prairie . . . but our news staff would not believe the stories. Nor did they ever take the pains to go out to see.” Nor did Cox. When the city editor of the Daily News, Dan Kumler, was asked later why for so long nothing was reported of the momentous accomplishments taking place so nearby, he said after a moment’s reflection, “I guess the truth is that we were just plain dumb.”
