I Heard, (Rumors), that DB Cooper, the Famous Hi Jacker, yet to be seen or heard from since 1971, is filing a Law Suit to have those bars removed from those 727 Jetliners and also in a separate lawsuit, for Using his name as reference to those bars , the Cooper Lock bar or whatever.
but then again,, ya know how rumors are
Kinda bout' 40 years too late, since you'd have a hard time even trying to find a commercial passenger 727 Jet flying now days, at least not in the USA anyways.
I don't think DB Cooper ever jumped out of that plane, personally,,,
I'll bet he took some money and a parachute, and threw it out the back, to make it look like he jumped out of that 727.
Then switched clothes, and walked right by all those FBI Agents and cops at the airport, and that's why his body has never ever been found, just some loot, found in 1980 by an 8 year old kid.
Walked right off that plane, and right by all those law enforcement agents, smiling from ear to ear, thinking you dumb idiots, you really think I'd jump out of an airplane in the dark, in a storm at 10,000 feet ??
What ya think I am, Stupid !!
The Blind, leadin the Blind !
Well, somebody fell for the BS Charade !
Makes for good Folklore tho !!
