Was Phil Schneider abducted near Snow Flake, AZ?
No. That was Travis Walton, IIRC.
I can't vouch for him being abducted by anybody. All I know is that he was an Army engineer who was whisleblowing about the Dulce 2-mile down dig and the firefight they got into with some greys.
I have one of his live small informal seminars he was conducting for a short period of time, after which he was found piano-wired to death on his own property.
