Ok, so I'm bored after my finals here at school, and I was reading a bit about the history of the 707 testing program. This, from Boeing caught my eye:
Quote: The Dash 80 flew with a fifth engine mounted on the aft fuselage to test installation feasibility for the trijet 727 and with three different types of engines installed at the same time. It investigated engine-thrust reversers, engine sound suppressers, rigs designed to cause in-flight engine icing conditions, air conditioners, and wing flap and slat modifications.
Googleing around isn't doing me any good. What were the results of these tests, sides the 727 , and does anyone have anymore information and pictures?

Reminds me of Pratt & Whitney's Boeing 720 used as an engine testbed.
