Ask an Explainer

Q:

What is the maximum theoretical altitude of an air-breathing engine?

A:

Theoretically, the limit would be 'space', where these is no air to produce thrust in an air breathing engine.

 

The SR71 Blackbird currently holds the record for maximum altitude of an air breathing engine and reached almost 85,000 feet.
