Cool Rate Problem from The Curmudgeon

July 20, 2009

This is a fun problem:

Military Science
This plane holds several records, including New York to London in 1 hour 54 minutes and Los Angeles to Dulles International Airport, outside Washington, D.C., in 1 hour 4 minutes 20 seconds. Built for reconnaissance, it relied on speed instead of weapons for safety. Operational from 1964 to 1990, this spy plane could fly three times the speed of sound. Name the plane.

BONUS: If the distance is roughly 2600 miles, what was the average speed from LA to Dulles?

DOUBLE BONUS: If the speed of sound is 770 mph, what Mach Number did the plane average?
