The US has been operating with air bosses and their assistants for decades, in war and in peace time, with very heavy tempos of operation.
They know how to provide the right shifting for those guys and maximize their experience, their availability, and their ability to apply the vast knowledge that they have built up without losing them to fatigue and sleep deprivation.
Where I work we have a group of operators who work in a central control center. They keep the place manned 24 x 7 with similar shifting as what you see on a carrier. They usually work four 12 hour shifts with spaced off periods so they can fill the operational schedule. There is one who is the Sr. Operator, and he could get called in at any time.
The Air Boss and the assistant air bosses work in a similar fashion, and have been doing so for decades. I am not aware of any serious, life threatening mishap that was due to air boss fatigue in my life time...popeye, kwaig, you guys worked directly with these guys for years, are you aware of any air boss fatigue leading to serious problems?
Not one that directly led to a mishap or accident.. most days they just cuss to let loose some steam and lots of coffee. To become an airboss, that individual usually already has many years of experience in aviation and flight handling and know not just their duties but have adapted to that type of work. You don't see young folks as airbosses.
Sometimes the miniboss steps in but working on the flight deck involves many dozens of men. The airboss is like a coordinator but everyone plays their respective role otherwise mishaps WILL happen and I have seen a few. Everyone from the shooter to the handler to the LSO for landing etc.. yellow shirts to the greenshirted guys have exact duties they need to perform to carry out the control chaos. It's simple.. if people don't do their jobs or are lackadaisical about it people die. It's that simple.
