Competing against Douglas and Martin for a contract to build 200 bombers, the Boeing entry outperformed both competitors and more than met the Air Corps' expectations. Although Boeing lost the contract due to the prototype's crash, the Air Corps was so impressed with Boeing's design that they ordered 13 B-17s. The B-17 Flying Fortress went on to eventually evolve through numerous design advancements.

A flight engineer was added to reduce the pilot's workload. The design specified powerful engines that were still under development. The prototype had to use engines with half the horsepower and, as such, the airplane had inferior performance and flew purely an experimental aircraft. This prototype was adapted with cargo doors and flew as a cargo transport during World War II under the designation XC-105 Patent Diagrams for the Boeing Model 294 Design Patent D-97,355 Click to Enlarge Click Here to learn how to get free patent diagrams Due to the multiple turret positions, it was believed that this aircraft could defend itself without fighter escort. The gunners had to operate in ultra-cold temperatures wearing oxygen masks. Numerous technological innovations, such as the electrically heated suits shown below, were developed to facillitate this self-defense capability. All, eventually, proved to be ineffective.

It was priced at $12.50 in the 1940s, something that would be equivalent to $400 today. These kits are rare and quite desirable today, often reaching prices over $500 in online auctions.
