Meyer Louie wrote That's a big IF. Everyone assumes that the sketch was an accurate depiction of DBC. I worked on cases where composite sketches were prepared, witnesses all agreed that the sketch closely resembled the perpetrator, then a guy is arrested, tied to the crime by solid evidence... and he looks VERY different from the sketch. Go figure. I've seen witnesses get height and weight waaaay off too. Sometimes they even got eye color wrong. I too wonder why Cooper appeared to take no significant disguise measures. But I've represented defendants who stuck up places they KNEW had cameras and yet they didn't put on a mask. I think Cooper was way smarter than they were. If Ted Braden was DBC he might have figured he'd spend his life in non extraditable exhile and didn't care if he was eventually identified. Because of my experience with police sketches, I don't assume that the FBI drawings closely resemble Cooper. I've seen too many cases where the drawings were highly inaccurate. 377 2018 marks half a century as a skydiver. Trained by the late Perry Stevens D-51 in 1968.

Jo wrote ??? Duane certainly knew how to get arrested. He had been arrested many times. It's impossible to believe that he couldn't manage to accomplish this when he wanted to. If you want to get arrested you go to the FBI, not to an identity change author. Your story, although quite moving, is pure speculation. If this was a suicide mission Cooper wouldn't have been so careful to avoid being shot through a window by FBI marksmen who would have been happy to fulfill a death wish. Whoever Cooper was, he took measures to avoid getting gunned down. Your theory that Duane would take hot twenties back into the crime area and toss them in the river makes no sense. That's unnecessarily risky. You claim he was so wary of being associated with Norjack that he wouldn't even let you watch a TV show about it. How would it make sense for him to transport evidence that could nail him? Duane's felony record would be disclosed by radio to any cop who pulled him over. When cops pull over a driver and learn that he's a felon, they almost always find a reason to do a search. It would be insane to carry incriminating evidence on a car trip. 377 2018 marks half a century as a skydiver. Trained by the late Perry Stevens D-51 in 1968.

If you give me that Regency TR1 I'll convert your old CRT TV into an X-ray machine Farf. Just take the CRT anode HV before it hits the rectifier tube and put it through a voltage tripler or, if you are feeling manly, a quadrupler. Those electrons coming out of the electron gun in the CRT neck will now be smashing into the phosphor with enough energy to generate some useable X-rays. An early CRT without leaded glass is best. If you want a smaller source just overdrive the HV rectifier tube. http://www.kronjaeger.com/hv-old/xray/intro/index.htm I soooo want a Regency TR1 transistor radio. All I have is a CK722 transistor. http://ck722museum.com/ If you want to trade your TR1 for a custom made CB-airband transceiver I'll have to get Snow's help. That's too tough a job for me. Listening to Galen and Bruce's radio appearance now. They go into a little paranormal tangent/detour but its a good listen. 377 2018 marks half a century as a skydiver.

A buddy of mine is an officer on a HUGE US flagged container ship. The skipper loves to fish. They poured on a little speed to arrive a few hours early off the Kona coast and believe it or not managed to hook and land a yellowfin tuna from the ship! The trolling exercise was logged as a "man overboard drill". 377 2018 marks half a century as a skydiver. Trained by the late Perry Stevens D-51 in 1968.

Very cool. Lew stated jumping in 1948!!!! Get him to tell you a lot of jump stories from back in the day. Very few of those guys are left and far fewer still jump. I met Lew at WFFC a few years ago and stupidly didnt hink of asking him to sign my logbook. 377 2018 marks half a century as a skydiver. Trained by the late Perry Stevens D-51 in 1968.

Liked your skinny tie poster farf. In this case a picture was worth a thousand words. I often wonder what is says about Cooper that he would drink Bourbon before such a dangerous jump. I jump sober and clean, always have. I have nothing against mind altering substances, its just that I dont want my mind altered or reactions dulled if I have a low altitude high speed malfunction. Not all skydivers share my caution though. Back in the day I was on DC 3 loads where jumpers were smoking pot and even snorting coke on the way to jump altitude. Never saw anyone boozing on the way up though. 377 2018 marks half a century as a skydiver. Trained by the late Perry Stevens D-51 in 1968.

Jo wrote Jo, You say you are an old lady with "nothing to lose" yet you tease about secret govt programs involving ex cons, etc. if you have nothing to lose then spill the beans. Do an exposé. Go public. Lets see what evidence you have to substantiate these spectacular claims. It's easy to tease and claim that national security prevents you from telling all you know. That story is repeated every night in a hundred bars by guys claiming to be spooks, spies, etc. Hope your health is improving.

Georger wrote Don't knock it. He said he could pull about $8000 dollars a day out of that hole. That's probably more than any of us make. I'd talk to squirrels and eat crow for a deal like that. I do wonder why JT completely disappeared from the forum. I met Jerry and his child bride at the Portland symposium. In person, JT was easy to get along with and not at all belligerant, even when we disagreed. He put me in touch with Himmelsbach who graciously answered a bunch of questions I had about Cooper's alleged familiarity with donning a parachute rig. 377 2018 marks half a century as a skydiver.

Jo wrote about the CB-airplane communication I dont think you are lying about what you heard Jo, I just think you misinterpretted it. The efforts of others to get you to understand and acknowledge your error has been for naught. We tried, we failed, we will let it go. 10-4? 377 2018 marks half a century as a skydiver.

Jo asked about smoke jumper radios for comms between planes and jumpers on the ground. Here is some info: http://forums.radioreference.com/federal-monitoring-forum/230608-smokejumper-frequencies.html Aircraft dropping retardant on fires are equipped with VHF FM radios such as Wulfsberg 9600 models. They use these to communicate with spotters, other tankers, ground fire crews and trucks. I visited an air tanker base at Chester CA a few years ago and all the planes had this gear installed. As I recall their channel cards showed freqs in the 160-170 MHz region.

21.964 is an HF aviation freq. HF is used when aircraft are beyond VHF range, typically on trans oceanic flights. What you hear on these HF freqs are mostly periodic position and status reports as an airplane progresses across an ocean. HF is not normally used by domestic flights and most airliners used on domestic flights don't even carry HF radios. As an aside, back when the forum was debating whether Coopers 727 carried radio teletype (RTTY) gear, I contacted a retired NWA 727 captain who flew in 71. He said none of the NWA 727s had RTTY gear and medium range NWA aircraft that were used exclusively on domestic routes didn't carry HF radios. In 71 727s were not used on long range trans ocean flights by any US carriers. Also, HF aviation radios use SSB modulation (USB). If you receive SSB on a CB receiver set up for AM reception what you hear is unintelligible. HF radios used to operate on AM but FCC, FAA and ITU regs mandated a change to SSB, sometime in the mid 60s as I recall. In summary, I believe that what Jo thought was an aircraft transmission coming through Duanes CB was not coming from an airplane. CBers spoof and impersonate all the time. A guy driving an old VW will tell others that he is a trucker driving an 18 wheeler. Maybe some CBer thought it would be fun to pretend he was a pilot talking from the cockpit. I've asked Jo to tell me what evidence she relied on for her conclusion that the communication she heard actually originated from an aircraft. She hasn't yet replied. I'm being EXTRA nice and won't hound her or ridicule her response. 377 2018 marks half a century as a skydiver. Trained by the late Perry Stevens D-51 in 1968.

Just to have a complete record, in the 70s many LARGE long range aircraft that did transoceanic flying had HF SSB radios capable of operating on CB frequencies in AM (actually AME, which is compatible with AM). The Collins 618T was such a radio and was common on long range airliners flying across ocean routes. The military also used them. They were far too big for light aircraft and had power requirements that no little Cessna or Piper could provide. http://web.tiscalinet.it/milradio73/radio_618T.html I've never heard one operate on CB, but it could. Famous air racer Lloyd Hamilton (deceased) had friends in the Bodega Bay commercial fishing fleet. When he was flying 707s for Pan Am he'd sometimes call on a marine HF frequency inbound to SFO near the CA coast. It was informal, no callsigns, just first names and a very brief chat with his fishermen friends. As I recall it was on 2638 KHz. Neither a 618T HF set or any CB could operate on normal aviation VHF frequencies. 377 2018 marks half a century as a skydiver. Trained by the late Perry Stevens D-51 in 1968.

Jo wrote Jo, Seriously, how do you KNOW the message you and Duane heard on the car CB came from an airplane? Tell me how you are certain about your conclusion. Are you willing to consider the possibility that it did not come from an airplane? If not why not? 377 2018 marks half a century as a skydiver. Trained by the late Perry Stevens D-51 in 1968.

Jo wrote Jo, In the 60s and 70s boats didn't carry any radios that could communicate with aircraft on the VHF AM band that airplanes use to talk to ATC and to each other. USCG rescue aircraft and some USAF rescue aircraft carried radios that could operate on marine HF AM (later SSB) and on VHF FM marine bands. Some USCG aircraft even carried radios that could communicate with ships on low frequencies (500 KHz and below) using CW Morse Code. So ordinary boat to ordinary plane radio communication wasn't possible. Some seiners had aviation band radios to talk with fish spotter planes and helos, but this was a special case and not common. I assisted a few times with sea rescues by handling comms with en route rescue aircraft on HF and relaying to the boat in distress that didn't have this radio gear. Frequencies I recall using were 2182 KHz, 11179 KHz, and 8291 KHz. There is no way you could have known for sure that what you heard on Duane's CB came from a plane just from the subject matter content. I've heard CBers pull all sorts of impersonations and tricks. It might have been some joker pretending he was a pilot. Trust me Jo, there was no CB radio that could also communicate on the VHF aircraft band, not then, not now. No "CB man" could make a modification that would give a CB this capability. 377 2018 marks half a century as a skydiver. Trained by the late Perry Stevens D-51 in 1968.

A different kind of rescue beacon called a SOFAR bomb. Found out about it in the Search and Rescue manual. Only useful in deep oceans, but very clever. 377 2018 marks half a century as a skydiver. Trained by the late Perry Stevens D-51 in 1968.

And the manual (written or updated in 1991) also has a lot of info on which radar systems record data and how long the data is retained. This isnt 1971 info, but I found it interesting as it listed a lot of recording radar sources that hadnt occurred to me. This book has a good explanation of how searches are conducted based on last known position, dead reckoning etc. Some of it would apply to how the Cooper search was planned and executed.

Farf, you've reached new Photoshop heights with the picture of your CB-GLC-Nav/Comm-HF-Whip-ator product. Blevins was right, it can be made. You've proved it.
