Flashback to 1981

Gemini Sparkle

Key Takeaways:

  • The Lear Fan was an innovative aircraft, distinguished by its advanced carbon fiber composite construction and state-of-the-art avionics for its time.
  • Its unique propulsion system featured two turboprop engines configured to drive a single pusher propeller.
  • Despite reliable engines, the aircraft's critical flaw and ultimate "Achille's heel" was the problematic gearbox system that linked the twin engines to the single propeller, which could never be perfected.
