What a rush it must be to start the C-17 Globemaster. When you start the 575,000 pound airlifter, you are actually starting 4 engines capable of 160,000 lbs of thrust.
Here’s a clip out of Travis Air Force Base, California that shows a timelapse of the engine start sequence for the Boeing C-17A Globemaster III. The C-17 is powered by four Pratt and Whitney F117-PW-100 engines. Normally, C-17 pilots start each engine off of the Auxiliary Power Unit (APU) in order from 1 to 4. This clip shows that “standard” start sequence, where the Pilot (left seat) starts numbers 1 and 2, and the Copilot (right seat) starts numbers 3 and 4. While this video is condensed to just 17 seconds, a normal start sequence can take about 30 minutes (from getting in the seat to ready to taxi), depending on the crew experience and exact method chosen to start the engines.
