No. Airborne dumps SUCK in most non P/C type aircraft.
Yea, and it generally doesn't involve flushing. Some things pooping whilst airborne does involve:
1. A large, heavy duty black trash bag. Or a helmet bag. Or, if you're one guy in my old squadron, a sandwich sized zip loc bag. At least it wasn't the flip top kind.
2. Figuring out which article of clothing you're going to sacrifice if you're SOL on the toilet paper front or don't have any baby wipes. You know the dump on the plane is definitely going to involve some serious clean up on aisle 9...I was always of the theory that my boxers would be the sacrificial lamb. Boots without socks is just downright uncomfortable, and no t shirt with your flight suit looks ridiculous, but a flight suit without boxers? Strangely liberating.
3. Deciding where you are going to put the biological episode once you're done with it. Doppler well? Next to your favorite O-4 NFO who just happens to be sleeping while you transit the straits of (insert geographic location near everyone's favorite bad guy country)? In the galley trashcan?
4. Determining how much your bar tab is going to be to pay for beers for everyone on board who has been graced with your essence.
5. Exhibiting the appropriate level of pride you're going to display as you walk what was formerly a part of your lower intestine into the nearest dumpster once you're safely on deck.
6. How strangely relaxed you are while rectifying the aforementioned biological incident even though you're shut in a closet with no windows, 3 out of 4 lights broken, flight suit around your ankles and your survival gear strewn about you, knowing the 2P and 3P are flying and that there's nothing you can do to help if the proverbial doo doo hits the fan. Good thing there's a fuselage rescue cut out that the instructors like to point out only takes an HOUR AND A HALF to hack through with a crash axe. Comforting.
