    Fly-In at KDRT.


    That would be "DRT" as in a dirt airstrip out by the Hassayampa and Flat Iron Mountain, north of I-10.

    I rode out to see some buddies (Anyone remember JimJib?), who were on an off-road riding weekend. This was their stop for the night. The dude with the plane is an old riding buddy of Jim's. Since he didn't have a bike ready to ride, he decided to take the plane.

    The airliner contrail is visible for a good 7-8 seconds prior to point of closest approach. This illustrates a real known problem with Head Up Displays (HUD's), basically you have a natural tendency to gaze at the display, not ahead and beyond. Airliners, the (few) ones with HUD's, do not use them in cruise flight, only for low visibility approaches. Military aircraft (as this one is, I suspect a low performance fighter trainer) use a HUD for low vis approaches but principally for target selection/aiming, and back up primary flight information when in tactical modes. This isn't to say the pilot was asleep at the stick, and it also makes one wonder why the passing airliner TCAS did not give a RA (resolution advisory) to turn well before this encounter. There seems to be some confusion about the aircrafts transponder altitude reporting too, and other issues with ATC. I.E. They seemed to know where he was, before and after the sector handoff. They supposedly should have known about the airliner, too. (Before the handoff the controller asked him to expedite to FL360, which is always a clue to be aware for traffic). The military plane was cleared to FL360, but later, with the second controller, he was told to immediately descend to FL320, after the encounter. Not knowing Italian I can't tell if he reported this near collision. Perhaps the previous controller did not forward t:freaky:freakyhe cleared to FL360 to the next controller and the second controller thought he was at FL320, even though he reported in at FL360. That, coupled with the apparent altitude reporting problems may have coupled to make a high threat environment it came to be.

    End of novel.

    If the fighter was really hauling, the closure could have been too fast for TCAS to resolve a solution.

    Or, perhaps the fighter's transponder was not sending or accurately reporting Mode C (pressure altitude).

    The Hud indicates about 240-250 KIAS, which at FL360 is around 450 true, probably about what the airliner was doing as well, which is within TCAS closure resolution.

    At least 3-4 problems:

    1. Pilot scan (at least 10 seconds visible with the contrail). This may be an artifact of the HUD, limiting the ability or inclination to keep scanning, especially under positive control airspace, i.e. ATC being responsible for separation. Pilot turned away when aircraft trajectory was a miss, but probably a (good) reflex.

    2. Some sort of mode C altitude issue.

    3. Confusion or misinformation between the controllers with the hand-off. If the mode C was out and the controller sensed this but believed he was told from the handoff controller the aircraft was at FL320 (and/or getting a strip for that altitude) he would not have been in a hurry to fix this since his traffic (the airliner) was at FL360.

    4. No TCAS with the airliner? It doesn't appear they were turning away from the conflict traffic.

    That's how many accidents occur, a cascade of issues "snowballing". (Newer term latent errors filtering through the swiss cheese safety net, when all the holes align...

    Beamer Bob,
    What a feeling right...I put a deposit on my new wings two days ago not my first one, had a few before.
    I'll post pics following delivery on April 4th. Don't want to jinx it...:clap

    Just doesn't look right to me, feet in the wrong position to start...scale of bomb bay to jumper is a little off...wrong angle of jumper in relation to aircraft direction and wind flow...

    It was posted by the collings foundation on their facebook a few days ago.

    "Great picture of Skydiver Randy Frazier falling out of the B-17 - taken by Peter Learmouth. - Thanks Randy!"

    Now this is something a bit special. This is sam, sam is a WWII vet, flew in B24s over europe and is a tail gunner ace! Quite a story teller and generally nice guy. He is pointing to his name in honor position on the tail of witchcraft. His crew eventually was shot down and had to land on an island off sweden/germany somewhere. They argued over his crew and finally were given over to the swedes and spent the rest of the war in an internment camp. :deal

    Yes he does! Going to see him again tomorrow and probably pick one up.

    Funny story is that he was shooting away at a bf109 that was trying to make a rocket pass on them. It finally got a rocket off that he tried to shoot, but missed. It went past his plane and blew up under the aircraft in front and down it went.

    One of the crew that was shot down from that plane is at the museum I work at. His name is Joe Reus and his a hellova guy too. Small small small world! :clap

    Like Marie Lou often said while bringing coffee and cookies at altitude "your'e only a pilot until we land" and I recall my first reply "Yeah... and then we turn into animals, What room are you in?" :sweeti:raabia

    I was on base at NAF El Centro over the weekend. One more trip next weekend for the airshow, and I'm done out there for a few months.

    We got some Harrier and Apache action as well. I'll post those up once I'm done with the PP.
