Piece o' cake.Very!
The Concorde comes close, but to get there you'd need a Tupelov
Well, I was thinking about a commercial passenger plane.Piece o' cake.
I actually did this for halloween (and I didn't know it was a thing). Also used half of a ping pong ball.
i tend to agree. the speed of sound is 768 mph at sea level at 68°F. it decreases as the plane increases in altitude, due to the air being thinner and less resistant. twice that would be over 1500 mph, and i don't think any airliner has reached that speed, ever.Twice the speed of sound is very fast!

At the altitude the Concorde flow Mach 2 is 1350 MPH and the Concorde flew at 1354 MPH which is actually a hair over Mach 2.i tend to agree. the speed of sound is 768 mph at sea level at 68°F. it decreases as the plane increases in altitude, due to the air being thinner and less resistant. twice that would be over 1500 mph, and i don't think any airliner has reached that speed, ever.
ok....ONE. pretty sure the seating configuration on that meme IS NOT the Concorde (see below)At the altitude the Concorde flow Mach 2 is 1350 MPH and the Concorde flew at 1354 MPH which is actually a hair over Mach 2.
