B-17 "Aluminum Overcast"

Aluminum Overcast, B-17G-105-VE, s/n 44-85740, civil registration N5017N, is one of only ten presently airworthy Boeing B-17 Flying Fortresses of the 48 complete surviving airframes in existence. It never saw combat, and it escaped the fate of many aircraft that were scrapped after World War II. It is owned by the Experimental Aircraft Association(EAA), and, as of 2018, it is still touring the United States and Canada offering flight experiences.

Through its association as the "flagship" of the EAA, Aluminum Overcast has become one of the most recognizable examples of the B-17, due to its extensive touring schedule with over one million flight miles accumulated. The overhaul and restoration of the airframe took more than 10 years and thousands of hours by staff and volunteers at EAA Oshkosh, Wisconsin, headquarters.[1] Aluminum Overcast carries the colors of the 398th Bomb Group of World War II, which flew hundreds of missions over Nazi-held territory during the war. Aluminum Overcast commemorates B-17G AAF Serial No. 42-102516, shot down over France in 1944.
