Thought I would provide my 2 cents worth.
Being a prior AWACS crewmember, the story that LimaNiner
has mentioned seems to be an urban legend. First of all, if it was a USAF
AWACS pilot who they talk about, he would not be flying if his security clearance was either out-dated or non-existant. Many AWACS crewmembers have sat on the ground waiting for their security clearances prior to flying on the jet.
The story went that every time he had to go to the bathroom, which is at the rear of the plane, all of the operators had to cover up their consoles, because "Top Secret" clearance is required to even see the screens
A "Top Secret" clearance is not required to see the screens. We have had crewmember's wives fly on the jet and they were able to see what was happening on the screens. So....you do not have to have a security clearance to fly on the USAF
AWACS. Anyone who is authorized to fly on the E-3 will be verified through some sort of program.
Now as far as the topic is concerned, the bathroom/lavatory on the E-3 is in the very aft of the jet and is similar to one on a commercial airliner. It is cramped and has just enough room for only one person. It uses the standard blue colored water and can get real nasty looking on long (over 12 hour) flights.There is no running water in the E-3 bathroom, instead you are provided with wet-wipes to use instead of water. There is of course toilet paper in the bathroom.
Now for a real humorous story. It took place (I believe) during Operation SOUTHERN WATCH. An E-3 was nearing the end of it's mission, but the toilet was full and ready to overflow. The crew asked an E-2 Hawkeye that was working in the area if they could control the last package of aircraft (all Navy planes) that was to enter the area because the E-3 had to RTB (Return To Base). The E-2 asked for the reason as to why the E-3 had to RTB early. The weapons controller responded using a calm and collective voice "The Shitters full". The E-2 took the mission and the E-3 departed the area and headed for home.
