"also page 65 testimony of S. Lewis Wallick, test pilot on the air stairs test of the 727 ( I think he was the test pilot. I didn't double check the report snip above)"

Lew Wallick was the pilot on at least one of the air stairs test flights.  He was also the 727 project pilot and made the first flight of the 727.

Turns out an AOA indicator provides very useful info for general aviation pilots. My son owns and flies a two seat carbon fiber Aero Shark with two very up to date glass panels. He not only has an a AOA indicator on each LCD panel but also a voice annunciator that will give a loud verbal warning if AOA increases beyond safe limits given other factors such as airspeed. He bought the plane used from an Air National Guard F-16 pilot. The seller gave him a lot of useful tips about AOA, info that was omitted from my son’s basic flight training. My son told me if you stay on top of AOA you will never have an unintended stall.

377

Glass panels came along well after I retired so I don't have any personal experience with them or with AOA instruments either.  But wings do stall at essentially the same angle of attack which depends on the flap/slats configuration among other things.  For a specific configuration, the stall speed varies as a function of the aircraft's weight.  But as your son points out, if you keep the AOA below the stall AOA for your specific aircraft configuration you won't stall.

As I mentioned previously, the Navy pioneered the use of AOA indicators.  I have heard that the Navy tries to keep the wind over the deck at a given value and will adjust the speed of the carrier to maintain that speed.  So presumably the deck touchdown speed of an aircraft will vary depending on the weight of the landing aircraft.  That is, identical configured aircraft flying at the same AOA will touch down at different speeds depending on their weight.

i made some other posts on Braden on the suspects pages

but here's an interesting braden story from 1944

FRIDAY, JANUARY 05, 2007
Second Battalion 501st PIR at Bizory, Belgium
December 1944 through January 1945

Preface

The following is this author’s description of the flow of events and action as experienced by the men of Second Battalion, 501 Parachute Infantry Regiment, 101st Airborne Division beginning on the 18 December 1944 and ending on 15 January 1945. It is based on veteran’s accounts shared with the author in personal discussions, written accounts by veterans, and documents on file in the National Archives in Washington DC. It is in no way meant to be an accurate or final account, but the most probable based on the author’s interpretation of the material presented.


Peter Broome, first squad, second platoon, Easy Co., recalls that the German listening post in front of his foxhole on the farm track in Bizory was very close. Being a baseball player, Broome always judged distances in terms of baseball. The German listening post was close enough to him that a good little league pitcher could knock the helmet off the man sitting in it from his foxhole.\

Harry Mole recalls sitting in the listening post one night as being no fun at all. “You start to see things. It gets a bit hairy all out there by yourself.”

A fellow Easy trooper, Ted Braden, would crawl out to the listening post alone just after sundown. He knew that by the time he was settled into the listening post two German soldiers would be making their way as quietly as possible from tree to tree along the farm track to their listening post only a few dozen feet away.

The Germans always sent two men to such an outpost for they knew one soldier might be tempted to make his way to the American lines and give himself up. Men on listening outpost duty frequently heard snoring from their German counterparts.

remember
Braden was out of the military for a while in 1971
so any chance of FBI latching on to him, would probably depend on either
a really indepth investigation like they did to civilian clubs in the usa
(FBI didn't do that though)

or someone calling in a tip on Braden.
no evidence of <even redacted< tips on macv-sog players.

The other thing people should be asking, is if Braden was so obvious, how come he wasn't mentioned until I introduced him?

And how, out of the Billions of possibles, did he pop out? :)

> The second issue that I have with Braden is that I have a hard time believing that his photos weren't shown to the stews. We know that he WAS investigated as early as Spring of 72 because a former MACVSOG member has described FBI agents interviewing him about Braden at a North Carolina drop zone. This seems accurate because of course he was a suspect. There should be no doubt that FBI agents inquired with the military about any ex-green beret types who could have done this and Braden's name surely came up. Braden was also a known rabble rouser at the time, due to his Ramparts interview where he exposed the info of MACVSOG running CIA ops in Laos illegally. However, I asked Larry Carr recently about Braden and he said it's a name he never came across at all in the case files. That was a long time ago and was before Braden was a "household name" in the Vortex, so maybe Carr just forgot about it.

I have a hard time believing this FBI interview story.
Braden, as far as I can tell, was never a suspect, nor investigated.
Be happy to find info otherwise.
I mean, I can easily find Sheridan was suspect #112

> Braden is one of a tiny handful of named suspects who I think still warrant further investigation. It's shocking he has never been featured in one of these TV documentaries. Although, that's really the impact of the wiki page. Most people are lazy and will just go to the wiki page (which gets as many as 500k hits a month). Braden didn't have a wikipedia entry until I made one for him.



The interesting thing about Braden, is that even though Pat his wife and his ex-MACV-SOG friends suspected him, apparently no one ever called the FBI and said "investigate Braden"

at least, not according to any records currently released.

Really need to do an FOIA on Braden.
If the fbi did investigate him with respect to a $250k insurance scam in the early '70s, per his wife Pat, that would be interesting info

I mean. divorce and a $250k scam in the right time frame.

Seems like a  "must-investigate-more"

I think Braden got a bunch of free passes because of Vietnam activities that were still secret.

One thing that always fascinated me was the ability of the MAC SOG jumpers to rendezvous after landing. Remember, they were in enemy territory and made their jumps at night.

377

reminds me of this beacon ad that was in the fbi files. It was an ad. I have to find it again

377: how come you don't have this beacon in your collection?

Larry was a big proponent of "cooper must be someone the fbi didn't investigate"

There are no records of MACV-SOG investigations in the fbi files.
So if Larry was consistent he would say "of course we should investigate vietnam.. because the FBI didn't"

I liked Sheridan and Braden because they were two aspects of Vietnam that people didn't expect.
Age.
and
Civilian and Military.

Neither of those are expected. Which is why the FBI didn't investigate, I think.

interesting 12/6/78 fbi files 72 page 352
verification of decal on the found placard (snip attached)

also page 65 testimony of S. Lewis Wallick, test pilot on the air stairs test of the 727 ( I think he was the test pilot. I didn't double check the report snip above)

he provides more detail..this testimony was provided on November 30, 1971
interesting he didn't provide full detail on "oh yeah, we did extensive testing with airstairs down"...
he provides info, but doesn't say how he knows. (on Nov 30, 1971)
it wasn't until much later that Boeing was fully forthcoming about their testing.

The details don't work out.
But to feed the "what if"

But Braden supposedly worked in the past at a tool and die company.
machinist?

Don't have his full work history. not sure when he started trucking.

One thing that always fascinated me was the ability of the MAC SOG jumpers to rendezvous after landing. Remember, they were in enemy territory and made their jumps at night. They had to stay quiet, and they couldn’t use flares or other visual signals to find each other. Turns out they used a portable low power AM broadcast band transmitter carried by the leader. All jumpers carried ordinary Japanese AM band transistor radios that had the normal internal ferrite bar antenna, which is very directional. They learned how to find the transmitter by swinging the radio receivers until they got a null, that is a dip in the signal strength. The null would point in the direction of the transmitter. Problem is that there is 180° ambiguity with these ferrite bar antennas. They could be pointing towards the transmitter or directly away from it. Somehow the jumpers resolved this ambiguity successfully, and always managed to rendezvous. Perhaps they noted a decrease in signal strength if they were walking away from the transmitter, and then could reverse course. 

Ted Braden was well-versed in this radio assisted rendezvous technique.
