Inside the military lab where they freeze and cook entire airplanes

Welcome to the U.S. Air Force 46th Test Wing's McKinley's Climatic Laboratory at the Eglin Air Force Base, Florida. The Climatic Lab, which began testing in 1947, is the largest climate testing facility in the world, a real torture chamber for airplanes.

In the laboratory, test engineers can create almost every kind of severe weather conditions from a blizzard blowing snow, freezing rain, and desert heat to humid heat, salt fog, and sand storms. Temperatures in this giant laboratory can range from minus 105 degrees to 165 degrees.

An ice and snow-covered B-1B supersonic bomber aircraft undergoes simulated arctic weather conditions during environmental testing in the main chamber of the McKinley Climatic Laboratory in 1986.
