What are UFO ‘waves’ or ‘flaps’ and when have they occurred?

UFO “waves” or “flaps” are periods of unusually intense UFO activity concentrated in specific geographic regions over defined time periods. These phenomena, characterized by dramatic increases in sighting reports, often involve multiple witnesses, various object types, and sometimes physical evidence. Understanding these waves is crucial for identifying patterns and potentially predicting future occurrences.

Defining Waves and Flaps

Terminology

Wave vs. Flap: Often used interchangeably but subtle differences:

Wave Characteristics:

  • Longer duration (months to years)
  • Wider geographic spread
  • Gradual build and decline
  • Multiple sighting types
  • Media amplification effect

Flap Characteristics:

  • Shorter duration (days to weeks)
  • More localized area
  • Intense activity burst
  • Similar sighting types
  • Rapid onset and cessation

Quantitative Criteria

What Constitutes a Wave?: Researchers generally agree on:

Minimum Requirements:

  1. Report Increase: 300%+ above baseline
  2. Geographic Cluster: Defined region
  3. Time Concentration: Clear start/end
  4. Multiple Witnesses: Not isolated
  5. Media Coverage: Public awareness
