In the recent photos of the Boeing 387, it appears that the trailing edge flaps are not the original type on the model. If I recall correctly (from old footage and photos from the 1950's), the trailing edge the 387's wing had a similar design to that of the production model 707. Was the wing reconfigured and if so, why?

The 367-80 has been modified several times to test various things. It did have triple-slotted flaps like those on the 727 at one point. Later it had a cofiguration known as "blown flaps" for another test. It has also had different landing gear to test landing on unpaved strips, a fifth engine mounted on the aft fuselage (also a test for the 727), and its original JT3C engines replaced by the JT3D's seen in the picture. At one point Boeing referred to it as "the most modified aircraft."
