Just a small correction
The Greenshirt is sitting in the pit where the aircraft type is input into the steam system, and gets a read out of the steam pressure, that is not a launch station,,,,and is open the entire time there are flights ops going on
The Yellowshirt is the man that controls the launch and orders it, when the steam pressure is right, the Greenshirt signals him, then the pilot salutes the Yellowshirt when the aircraft is at full power, immediately pushing his head back into his headrest , and the Yellowshirt touches the deck in a pointing motion
at that point, the Shooter pushes a button in that "optional" bubble, releasing the cat shuttle, breaking the hold back rod, pushing the aircraft off the deck,,,,,,,,the Shooter was and is located in the deck edge catwalk for all the early ships that didn't get the retractable "bubble", which would be early Nimitz class and older ships
to get a successful launch with the new system, the holdback has to be in the correct notch in the deck, the cat shuttle has to be "tensioned" correctly on the nose gear, the steam has to be input and wound up, the aircraft has to be at full power, the pilot salutes the Yellow shirt, and the shooter pushes the shoot button
The system can still use a Bridle if it really has to, the hold back cable notches are still in some of the Cat Tracks on the older Nimitzes
Rex, Bridle and Van Velm era Blueshirt Jarhead
ps, just a touch of logic for any that doubt this,,,,,,,how would the Greenie know that the Yellow behind him is touching the deck in the kiss-off signal?,,,,,he sure wouldn't have seen it !!
