Why This Case Matters

A useful late-testimony case because military credentials and detailed narrative initially sound strong, yet the contemporary 1947 record is conspicuously silent.

Chronology

  • 16 Jul 1947 alleged B-17 encounter
  • no contemporary report located
  • decades later retired colonel provides account
  • story enters modern UFO databases
  • archival cross-check finds no matching 1947 record

The Witnesses
