The speed at which an object must travel in order to escape from the object which it is orbitting.
The Apollo 11 spacecraft had to travel at least 7 miles per second (11.25 km/s) to break free of Earth's gravitational field.
This speed is 32.4 times as fast as the speed of sound ('Mach 32.4"). The fastest military plane, the SR-71 Blackbird, travels (only) Mach 3

Apollo 11 was powered by a Saturn V rocket which stood 364 feet (101.5 meters) tall. It weighed 525,500 pounds (239,725 kg), empty;
and 6,100,000 pounds (2,766,913 kg), loaded.
The Statue of Liberty stands 152 feet (46 meters)

Apollo 11's Saturn V rocket required 4,325,132 lbs (1,965,969 kg) liquid oxygen; 1,432,662 lbs (651,210 kg) jet fuel (kerosene); and 202,851 lbs (92,205 kg) liquid hydrogen

Apollo's Saturn V's five boosters generated a total of 7.5 million pounds of thrust at liftoff.
A Boeing Passenger 747 produces 188,000 lbs of thrust (four engines each producing 47,000 lbs). [The Apollo launch produced thrust equivalent to forty 747's.]

The Apollo 11 spacecraft was equipped for its mission to the Moon with a state-of-the-art on-board computer.
The CPU ran at a pace of 1 Megahertz, and the system memory was 36K in size.
Currently, the typical home computer is equipped with a CPU running at least 300 MHz and many hand-held calculators contain more than 36K memory.
