Boeing's Phantom Eye drone achieved an altitude of 4,080 feet and a cruising altitude of 62 knots in its initial 28 minute flight.

A "cruising altitude of 62 KNOTS"?
Someone needs to whop KNOTS on that writer's head.
For the record, A KNOT is a nautical measure of speed through a fluid, whether water or air.
Altitude is self-evident. It is height above some reference, and has nothing to do with velocity in any direction.
And if the itent was to note 62 knots of airspeed, that is a fairly UNimpressive speed of only around 54 MPH, if I remember conversion right.
But the whole thing, even if 62 knots IS impressive to the reader, falls apart due to the laxity of editing/writing in the headline.
