Key Takeaways:

  • Cessna's 407 project aimed to develop a four-place civilian personal jet by modifying its existing T-37 "Tweet" military jet trainer, reversing its usual approach of adapting civilian aircraft for military use.
  • The company sought to enter the blossoming personal jet market with minimal investment by utilizing many components and tooling from the T-37, while incorporating design changes like a pressurized cabin and easier entry.
  • Despite building a full-scale mock-up, commencing prototype construction, and promising impressive performance, the 407 project was ultimately abandoned.
  • The 407 was shelved in favor of developing the highly successful Citation family of business jets, which first flew in 1969.

The late 1950s and early ’60s saw a frenzy of aircraft development. Largely driven by military contracts that called for a specialized type dedicated to each role, variety abounded, and unique designs emerged to address the many military requirements of the era.

Cessna was no exception, and it took an interesting approach to developing a new model in September 1959.
