There is a 20-Minute Warning, followed by a 10-Minute Warning, then a 6-Minute Warning.
Then, the command to the 'troopers is 'GET READY!
Followed by this sequence of jump commands:
****
'Outboard Personnel Stand Up!'
'Inboard Personnel Stand Up!'
'Hook Up!!.'
'Check Static Line!
'Check Equipment!'
'Sound Off For Equipment Check!'
'STAND IN THE DOOR!
'GO!!!'
****
'Hook Up! comes after 'Stand Up! and if you look, you'll see that the static line's secure.
That's how it was when I was a Jumpmaster...
Cheers!
Airborne!
