At their current altitude of just over twenty-thousand feet, the Tomcats could manage about Mach 2.3.

The water of the lake, still several thousand meters below their current altitude, was a deep, intense blue, like liquid oxygen.

In Norden's version of the system, the bombardier first looked up the expected time it would take for the bombs to fall from the current altitude.

The cave has a lot of evidence of marine life indicating that despite its current altitude this was a sea cave.

Users can also view data on the plane's current altitude and flight direction.

The top of descent may be calculated manually as long as the distance, air speed, and current altitude are known.

"Helm," Riker ordered, "maintain orbit over those lakes at current altitude."
