Strictly speaking, it was probably already through the sound barrier. The chances of that being the moment it broke through are fairly slim. The sonic boom's there the whole time it is (sorry, was ) supersonic. Good video, though.
Sorry, it's been a couple of days since my last incidence of being pedantic.

You know you are an aviation enthusiast when the sound of a sonic boom makes your eyes pop out and your jaw drops to the floor with excitement. All the vids on that page are freakin' awesome! Thanks alot for sharing that.

Very cool video though. Concorde Captain Les Brodie scared the living crap out of about 80 people during a seminar at last years London Air Show with that clip.

Brilliant video, i've never heard Concorde breaking the sound barrier. One question though, do the passengers hear the two loud bangs.....as loud as people on the ground?

Answer? No.
They are travelling faster than sound, they have passed where the sound is, so no chance.

Seeing that video has given me a totally new perspective of Concorde. I remember vividly the day it came to Guam. What a rare and opportune moment it was for anyone living out there to see her majesty. For those on the island that did get to see her when she visited us, the appreciation for the moment is much more profound now that she's not in service. I will share this video with my fellow enthusiasts back home. I'm sure they'll love it just as much as I did.

Brandon

To clarify for everyone that never got to fly her. All you feel our hear was two pushes in the back. At least for me. It was such an amazing journey for me. i only wish it would have been double the time.

And if they did it would be really annoying! It isn't a one-off event as the speed of sound is exceeded - it happens continuously all the time the aircraft is supersonic.

Arsenal@LHR, one BA Capt put it best over the PA;
"No bumps, no bangs, Concorde".
You did feel two slight nudges, just before Mach 1, they were the reheats being engaged, two at a time.
GuamVICE, as you probably know, Guam was a frequent stop over for Concordes doing round the world charters, BA were last there in Oct 99, with G-BOAD.
The last BA RTW, as planned at the time.
It features on a DVD, with a camera crew onboard, available from; www.concordesst.com/books.html

Did you know that the woman in the video is the wife of the pilot who was flying [i['Le Concorde'[/i] passing overhead that day?! I saw that video in a programme on 'Dicovery Wings' channel about the crash of F-BTSC. BTW, that's is the plane (BTSC) flying in that video.
but wasnt that bang happening all the time that concorde was going super sonic,
e.g. being the reason it couldnt fly supersonic over land.
rather than that just being the actual moment when it passed the sound barrier. pretty sure thats right??
Yeh your right about that, the people a few miles behind the cameraman would have heard the two bangs a few minutes before they did and anyone a few miles in front of the cameraman would have heard the two bangs a few minutes after them.

GDB,
I flew Concorde a number of times in service and I am worried that my memory is playing up with me as my recollections of going through Mach 1 were different.
After we went out over the Solent on one flight I clearly recall the captain saying reheat was not applied until it had exceeded something like 1.2 and would be kept on until 1.7 and about 47,000 feet was reached and then we would 'drift up' to about 54,000 feet and hunt up and down for the right combination of speed and nose temperature.
The push through the sound barrier was itself very gentle. The wonderful bird just surged ahead, the Mach counter flipping over 0.99 then 1.00 then higher in almost no time. Indeed the subsonic phase was very serene once the drop nose had been raised, while above Mach 1 you could hear the friction (and feel it after a while as window heat).
You certainly felt the afterburners come back on, just as you noticed them coming off after those exceptional takeoffs. When the transonic climb phase was over you also felt them come off again.
Out of JFK the transition seemed much faster I assume because there was no land within range of the boom.
It was a comparatively rare and superb experience to fly Concorde. Because of my antiquity I will never fly in the successor which surely comes...one glorious day.

No, the reheat had to be applied to go supersonic, this was true of all flights, it could not do it on 'dry' power.
But it was disengaged around Mach 1.7
Mach 2 was reached around 50,000 ft.
On my 7 flights, I never noticed much the nudges of reheat application, until my last, OAE's retirement to BGI, but then I was in the very last row, rear cabin, also standing up at the time.
I am puzzled why any Capt would say reheat engaged at Mach 1.2/3, was he referring to something else?
The only thing I can think of are the intake ramps, to control the airflow into the engines, keeping them at acceptable speeds for the engine, usually these began working at Mach 1.3.
