An Aircraft Built for Speed Loses Power

Key Takeaways:

  • The replica Bugatti-de Monge 100P racer, "Le Rêve Bleu," crashed on its third flight in 2016, killing its highly experienced pilot, due to a low-altitude stall after an engine anomaly (likely a slipping clutch) caused a loss of power.
  • The aircraft's complex drivetrain, heavy weight, extreme wing taper, and fixed-pitch propellers contributed to its difficulty in maintaining airspeed and climb performance, particularly when operating "behind the power curve."
  • Despite the pilot's extensive experience and likely preparation, his failure to maintain airspeed by lowering the nose during the power loss highlights the unpredictable nature of human reaction under critical stress.

In August 2016, Le Rêve Bleu, a replica of the prewar Bugatti-de Monge 100P racer, crashed on its third flight. The pilot, 66—a 10,000-hour ex-U.S. Air Force pilot holding an ATP (airline transport pilot certificate), who had devoted years to the recreation of the fabled airplane—died.

The original airplane, now in the EAA museum, was built in the late 1930s. It was stored, incomplete, when World War II loomed, and it never flew. Intended to compete in the Coupe Deutsch de la Meurthe races, it had a drastically tapered, forward-swept wing (with an aspect ratio of 3.3), a minimal empennage, and contra-rotating tractor propellers driven by two Bugatti supercharged straight-eight engines of 450 hp each, mounted amidships, one behind the other. Racing speeds in those days were around 300 mph—the dominant competitors in Europe were carefully streamlined, but conventional Caudron monoplanes with six-cylinder inverted, inline engines of around 300 hp. Clearly, the Bugatti, if it worked, would be faster. Besides, some people thought it was the most beautiful airplane ever.
