A Formation of Dissimilar Aircraft Unravels

Pilots are endowed with the right to take risks.

A contributing factor, the NTSB said, was “the stepped-down configuration of the formation flight which was composed of dissimilar aircraft.” NTSB

Key Takeaways:

  • A mid-air collision occurred between two highly experienced pilots during a recreational formation flight in 2017 while performing a maneuver to change aircraft formation.
  • The NTSB attributed the accident to one pilot's failure to maintain clearance, citing the "stepped-down configuration" of dissimilar aircraft, which likely created blind spots, as a contributing factor.
  • The investigation criticized the informal "Gaggle Flight" formation group for its lack of structured training, evaluation, and certification standards, contrasting with more formalized formation flying programs.
  • The incident prompted some residents of the Spruce Creek community to re-evaluate the inherent risks of informal formation flying, despite initial resistance to the NTSB's call for stricter protocols.

On a Saturday morning in April 2017, a swarm of airplanes—40 pilots attended the preflight briefing—took off from Spruce Creek Airport in Florida for a flight to nearby Titusville to attend an EAA pancake breakfast. The Saturday morning breakfast flight to various destinations is a tradition at the private airstrip, the centerpiece of a gated community with a population of several thousand residents and hundreds of airplanes.
