Boeing launched the B-17 prototype on July 28, 1935. Known then as ‘Model 299’, it represented the ultimate in state-of-the-art technology. The plane boasted four turbo-charged engines, a hulky frame, twelve .50 caliber machine-gun mounts, and the ability to fly higher and longer than anything previously built.
The U.S. Army Air Corps designated the plane as the B-17. Used as a strategic weapon, it quickly took on a reputation of mythic proportions. Yet, by the end of WWII, technology had surpassed the B-17 and the plane was considered all but obsolete. New planes featured pressurization, hydraulics, heat, longer range, and larger bomb loads including rocket technology.
Today, in both the achievements of the plane itself and those who flew it, the B-17 remains an icon of American intelligence, resilience and achievement.
Facts
The rugged bomber simultaneously held the ability to defend itself, carry large bomb loads, absorb extensive battle damage, and still fly. During an early test flight it was nicknamed a Flying Fortress by Richard Smith, an observing reporter from the Seattle Times. Boeing embraced the catchy term and quickly trademarked it for use.
