Mr. J.B. Milnes Special Agent in Charge Federal Bureau of Investigation 1015 Second Avenue Seattle, Wash. 98104 February 1, 1972 Re: Your letter of Nov. 29th, '71l Dear Mr. Milnes: Thank you for expressing your appreciation of my observations. I see someone else had observations along the same line and put them to good use in a later hijacking. I fail to see, however, why the Air Force allowed the parachute bugging to be printed in the papers. I hear now there is great alarm concerning the number of hijackings recently. Among other things, I'm sure another escape is feared. I have given this matter some thought, and therefore, I have another observation you might benefit fron: The only obvious deviation from the established pattern "Mr. Cooper" used that has not been tried is to actually jump from the plane with the hostage. If the hijacker has a small plane or car as an escape vehicle and a pre-determined jump-site, he could pull it off. Parachutes can be designed to control the rate of descent via draft holes in the top center of the silk, I believe. Therefore, the wgy to foil the escape would be to radically vary the descent factor of the parachutes. ie: one drops quickly, one floats for a long time. This would separate the hijacker from his hostage and foi} his drop; meanwhile helicopter teams could rescue the hostage, subdue the hijacker, while the Air Force could track the escape vehicle. This idea would probably not work as smoothly as presented here, but it is a way to stop such an occurrence. You may rest assured I keep these ideas to myself, and for added credulence, I was granted a security clearance while employed at the Boeing Co. Thank you for your time. I don't expect you to reply to this letter. Just keep it in your hip pocket, just in case, Lf. SEARCHED__,__INDEXED____ FEB co 1972 yy FBI... SEATTLE es 7 DB Cooper-6303 J
