Mach 22!!
From today's Grauniad:
US military to launch fastest-ever plane | World news | The Guardian
Wonder what the VRef is?!!
By the time you finish reading this sentence, the Falcon HTV-2, the fastest plane ever built, could have flown 18 miles. It would get from London to Sydney in less than an hour, while withstanding temperatures of almost 2,000C, hotter than the melting point of steel.
At 3pm BST on Thursday , the US Defence Advance Research Projects Agency will launch the Falcon Hypersonic Technology Vehicle 2 on the back of a rocket from the Vandenberg Air Force Base in California. If all goes to plan, engineers will launch the Falcon HTV-2 to the edge of space, before detaching the plane and guiding it on a hypersonic flight that will reach speeds of 13,000mph (about 20 times the speed of sound) on its return to Earth.

Huh,
so much for
At 13,000 mph it takes 1/722.2' of an hour to travel 18 miles, which is almost 5s, and I can read that sentence in WAY under 5s.
I want my money back.

Perhaps they could have a range of planes that travel different distances according to how quickly one reads? Just a thought...

For the record the mission seems to be a failure, word is that the vehicle lost control during the glide.
Still, at least the X-37 is good at this stuff.
