Jet Engines and Starting Handles
You can tell I've been somewhere again, I'm back with a question.
VS20 from SFO leaving the 6th, we pushed back and sat there for much longer than normal with the engines not running. Then a bloke wearing ear defenders and a hi-vis jacket (and other clothing!) appeared and stuck what looked like a starting handle into the #4 engine, after which they all came to life.
What was that about?
