A massive cheat tbh, but clocked this on the Eurostar back from Brussels yesterday. Still astonishing though; those trains certainly shift, and it's effortless...
Even more of a cheat, clocked 707mph coming back from the States last year, with a favourable following breeze. I think I've had 740 on a similar trip but even I'm not quite anal enough to find it. Left it on the GPS for a while in case I needed to impress the Bill - that would be quite something for an airhead!

Hello,
I once (genuinely) travelled at 1,354mph...
...anyone care to guess how?
Best regards,
David

Hello,
Got it in one! Faster than a bullet from a gun....apparently
Childhood dream come true. Went up to the flight deck (In the days when you could) and saw the curvature of the earth out of the front window.
Best regards,
David
How fast?

How fast does the earth go when travelling round the sun? Or doesn't that count?

Watched a programme last night about Concorde on a DVD a friend gave me. What a machine!!
Very envious of your flight.

This is my GPS fastest speed.
But this was on Skis and I was aged 55 at the time. I spent a week skiing in Niederau Austria and when I added up the weeks stats I had skied down the equivalenmt of over 120,000 feet and had covered 147 miles (going downhil on skis as opposed to going up hill on chairlifts).

I once did approx 500mph...at an altitude of approx 200 feet. That felt quick.

I think it's speed changes, according to some geeza named Kepler.

The mph thing with aircraft gets interesting because you're not contacting the earth. Mmmm. ( strokes chin)

Flying over London once my TomTom on the phone was going nuts with speed camera warnings at 300 mph

Do gps systems know your road speed from Doppler shifts? Does it matter the altitude of the road? Does that affect accuracy?

I don't have an avatar. How about a voodoo doll.
With LOTS of pins in it?

I've traveled towards the earth using my own weight at approximately 125mph
