I am starting a small series on the "odd variants" of some aircraft types. This is the first post ๐ Please upvote if you would like to see more โ๏ธ
Honeywell owns a 757-200 with RR-engines. They have fitted their 757 with a small, 3rd, wing to test avionics, engines and other instruments. So far it has carried a jet engine, prop engine and instruments..
It is an early 757 from 1983: the 5th delivered 757. Delivered to the now defunct Eastern Airlines. Honeywell aquired it in 2005 as N757HW.
Haha, Google the registration (N757HW) and you will find some nice additional photos from other angles of this aircraft. Some photo-angles definitely look like if the aircraft is not real.
How would this aircraft behave in-flight? With the added drag on the 3rd-wing side, the aircraft will most likely pull to that side. Imagine flying a cross-wind landing and having the added drag. Nice pilot challenge ;-)
