I went London to New York. It was an evening flight, on G-BOAE. Felt the effect of the afterburners being relit somewhere after the Bristol Channel, with the Captain describing what was about to be done. Forget which way they were switched on - inner engines first, then outer?
After that, climb to cruising altitude, watching the Mach display to 2.0 and height to 60,000ft, then look out of the window to the blue and the black.
Occasionally, a subsonic craft way below, sort of going backwards.
And then, it's time to decelerate and start the descent. I wish it was longer, "up there".
If I had the money, I wouldn't go on one of these new rocket trips to get up there for all of a few mins.
Get on a vomit comet for the weightlessness, and yes, take the balloon. Far more time to savour the experience. And please, please keep the mobile behind and do look with your own eyes, and not through a screen / viewfinder.
