Gotta ask for those of us not on the inside with pilot/aircraft slang...what's a sewer tube!?
A Metroliner. Per Wiki.-
The Fairchild Swearingen Metroliner or the Fairchild Aerospace Metro is a 19-seat, pressurised, twin-turboprop airliner first produced by Swearingen Aircraft and later by Fairchild at a plant in San Antonio, Texas, United States.
From http://www.b737.org.uk/aircraftnicknames.htm Metroliner: San-Antonio sewerpipe, Texas Sewer Pipe, Death pencil, The Screamin Weenie, Texas Lawn Dart, Swetro (It got very hot in the summer), Baltimore Whore (no visible means of support, skinny lil ‘ol wings), Terror Tube, “That noisy f@#$ing (ed.) thing”, Widow maker, Kerosene Crowbar, Fear tube, Necroliner, Buzzbomb.
I guess us Northerners preferred sewer tube to sewerpipe.
