D.B COOPER MYSTERY: DID HIJACKER PUBLISH MEMOIR??

REAL?

THE MYSTERIOUS crook who pulled off America's biggest hijacking may have released a memoir, taunting authorities about his audacious crime.  

The newly unearthed autobiography, tauntingly called "HA-HA-HA" has a drawing of a man in a suit holding a briefcase while parachuting from a jet.  

The author claims to be D.B Cooper - the name given by the mystery passenger who escaped with $200,000 during the 1971 crime.  As we reported here the man waited until the Northwest Orient Airlines 727 flight took off before the man who gave his name as Dan, handed a flight attendant a note: 'Miss, I've got a bomb, come sit next to me — you're being hijacked.'
