#onthisday 1969 Concorde broke the sound barrier for the first time We just happen to have a prototype in the Science Museum Group collection (because, of course, we do) http://ow.ly/4pzG30m141d 

Let's go 'supersonic' with a little more Concorde memorabilia, shall we?

These wind tunnel models from the 1960s were used to develop Concorde's distinctive wing shape that helped it get to Mach 2 That's twice the speed of sound https://collection.sciencemuseumgroup.org.uk/objects/co240774/wind-tunnel-models-of-concorde-c-1960s-aircraft-aeroplanes-airliners-passenger-aircraft-research-aircraft-fuselages

That meant it could reach New York in just three and a half hours But how to fill up all that time? On its first flight in January 1976, you could have joined these gentlemen and snacked on some cheese and biscuits...

...or how about regaling your fellow passengers with your copy of the 23-mile-a-minute-fact-sheet? https://collection.sciencemuseumgroup.org.uk/objects/co8413583/concorde-fact-sheet-brochure

Or, if you need a bit of me-time, you could have popped on some headphones and grooved along with Supersonic Stereo No Oasis though... https://collection.sciencemuseumgroup.org.uk/objects/co8413578/concorde-in-flight-entertainment-brochure-brochure
