1 Revisiting One of the Classics— The Nash/Fortenberry UFO Sighting 14 July 1952 Thomas Tulien Most human affairs happen without leaving vestiges or records of any kind behind them. The past, having happened, has perished with only occasional traces. To begin with, although the absolute number of historical writings is staggering, only a small part of what happened in the past was ever observed…And only a part of what was observed in the past was remembered by those who observed it; only a part of what was remembered was recorded; only a part of what was recorded has survived; only a part of what survived has come to the historians’ attention; only a part of what has come to their attention is credible; only a part of what is credible has been grasped; and only a part of what has been grasped can be expounded or narrated by the historian. —Louis Gottschaulk, Understanding History (1969) Click to enlarge
