Hello,
Got a question for the older folks. It is well known that the Dash 80 was rolled out as the prototype for the 707 in 1954 and was barrel rolled by Tex Johnston in 1955.
Let's take a look at a few pics.
This is the -80 as it rolled out in 1954. Note the wing roots have a short chord with a fillet joining the trailing edge to the fuselage.
This is the -80 that now resides at Dulles Airport. Note the wing has a much longer chord and does not have the fillet.
Some captures from the footage of Tex's roll. Note it is the thin chord wing.
What's the deal here? Were flaps added to the -80 during later stages of development that resulted in the larger wing? This would also mean that Tex did not demonstrate the -80 in the configuration it presently exists in.
P.S. Click on any image to enlarge it.
