#PanAm launched Boeing 377 Stratocruiser service from San Francisco to Hawai’i in April 1949, and transatlantic service to London in June 1949 as all first-class “President” service. #WingWednesday This tweet was posted on May 12, 2021.

The aircraft’s four 28-cylinder Pratt & Whitney radial engines enabled the Stratocruiser, as its name asserted, to cruise in the stratosphere at over 300 miles per hour. With a range of just over 4,000 miles, the B-377 was ideally suited for transoceanic routes. #WingWednesday This tweet was posted on May 12, 2021.

Despite the "spruce" nicknaming, the H-4 was actually constructed primarily of birch due to weight concerns and restrictions on the use of aluminum during WWII. Numerous delays prevented it from being completed before the end of the war. #WingWednesday #avgeek This tweet was posted on May 05, 2021.
