Space:
I was in one of those tankers, it is nice to be appreciated
Teddy:
All the L188 tankers had to have the tail cone sealed to prevent the tail filling up with retardent and screwing up the elevator and rudder control booster packs. Every Tanker comes back with the whole belly smeared with residual retardent right to the back. Since the 146 will almost always be bombing with the spoilers out so keeping the inside of the spoilers from getting gummed up will be a challenge for all the conversions.
