Thats some serious speed, would that pic be one from the simulation?

Don't think so. Think that's the real thing.

 

It's great that they've got a working scramjet, but the problem is adapting it for use in everyday life. I don't think we're going to see any jumbo sized scramjets for a while yet

Forerunner to the next shuttlecraft, replacing the fleet of rockets with scramjet base jets with retrothruster for high altitude gain. If the scramjet is working, they just strap one onto a space worthy plane and staple a rocket to the other side.

 

Very Dan Dare.

if you talked while going the speed of sound what would you hear?

[atinymonkey]

If you are in a pressurised cabin, it would be normal. If you were outside of a cabin, probably you would hear your last scream before you died.

 

The coccon that the cabin provides means that vibrations travel just the same as they would on ground.
