An investigation of the mysterious April 15, 1995 crash
of a presidential helicopter near Washington, D.C.
in which the victims suffered radiation-like burns
and which was sparsely covered by the local and
national media.
The previously posted work is fiction, but it is based on a real account of a helicopter crash in the Washington, DC area in 1993 in which the victims had strange burn marks on their skin, etc.
Frank Owens investigated the crash. His web site is here.
