Not sure about the facilities on them..During the the Iraq war the crews had to buy folding aluminum chase lounges from Walmart. They would take turns “streaching out behind the flight crew stations. They’d fold ‘em up and bungee cord them to the bulkhead during the attack phase of the mission . The missions were 44+ hours if i recall
That’s why they have pee-tubes and collection bags.
I once briefed some Marine F-18 pilots (10 or 12 of them) who were flying non-stop From Lajes Field, Azores to Southern California. They briefed the times they were to take their pep pills... I forget how long the flight was but you couldn’t pay me enough...zzzzzzz. (They all made it safely, BTW)
Once a squadron came over from Louisiana all the way to RAF Bentwaters, England in a non stop flight. They each had two 600 gallon wing tanks and I believe they had to refuel at least once.
And, remember that the A-10 had no auto pilot back then so it was hands on stick the entire way. Those pilots could not wait to get out of those planes.
