I happened upon "Psychedelic Monster" N6578D when the Valiant Air Command was looking after her at Tico in Florida in 1984 - she was sharing ramp space with the one and only Bird Innovator N5907.
Looked her up and, very sadly, it seems she has fallen on hard times and is looking very neglected at
Franklin, Virginia. Hope someone can wave the "$$$$$ no object" magic wand...
