| Al Stenzel ST. Louis, MO | I earlier wrote that the remaining YAV-8B was "sitting in the weeds at Spirit of St. Louis airport." That's wrong as I recently learned from the curator of the St. Louis Aviation Museum. He told me what I saw in the weeds was the lightning-strike test vehicle which was like a YAV-8B but with a wooden mock-up wing. It never flew but was used as a target for lightning strikes at the lightning facility outside Bldg 42 at McDonnell. 05/13/2008 @ 16:53 [ref: 20865] |
| LCDR Scott Schneeweis Sierra Vista, AZ | Can anybody here identify the location of the servo control unit on the aircraft (YAV-8B), its function (a picture or diagram would be great) and I know this is really pushing the envelope - a potential location to acquire a surplus unit to support restoration work?
Request the courtesy of a reply to my email address spaceaholic@gmail.com Many thanks - Scott 05/13/2008 @ 07:13 [ref: 20860] |
| Bob McNabb Mesa, AZ | For more information on "Y" designation such as YAV8B, www.google.com type "y prototype aircraft" and click on "Aircraft Designations". 10/22/2007 @ 23:04 [ref: 18281] |
| Bob McNabb Mesa, AZ | The "Y" indicates that that model is a flying prototype for flight testing. In the case of the McDonnell Douglas Harrier Air Craft there were two flying prototypes for the AV8B Harrier which were YAV8B S/N(ship number)1 Tail Number 158394 & YAV8B S/N 2 Tail Number 158395. S/N 2 crashed and S/N 1 was renumbered and transfered to NASA as N704NA and should be on display at Aviation Challenge Museum in Huntsville AL.

| JOHN LOCKE , TX | I GOOGLE MYSELF EVERY NIGHT!!!!!
IT MAKES ME FEEL GOOD!!!!!!!!!!! 10/17/2007 @ 17:32 [ref: 18227] |
| Erica Norfolk, VA | I'm in the Navy, aviation side. We were looking at the YAV-8B as opposed to the AV-8B. The "Y" kinda stood out and we were wondering where it came from. We googled it and found this website...very informative, but I was wondering if anyone would know what the "Y" designator stands for and where I could find the meaning of it...like a publication or something. If so, the sooner I find out, the better...it's kinda like a homework contest. 09/13/2007 @ 16:45 [ref: 17916] |
| Robert McNabb Mesa, AZ | I have a correction to previous posting. YAV8B S/N 1(158394) did not crash. It was YAV8B S/N 2(158395) which crashed at Lake of The Orzaks Missouri on 15NOV79. Flight test pilot John(JET) Jackson ejected safely. I was the liasion planner(manufacturing engineer) assigned to Bldg. 42 and member of first flight team with pictures of both YAV8B S/N 1 & 2 first flight team. Charlie Plummer was flight test pilot of S/N 1 and Jet Jackson S/N 2. YAV8B S/N 1 was later transfered to NASA.
I recently met at a Chick Fil A over night opening in Avondale, AZ Ben & Shannon Grasso, with baby daughter. Shannon overheard me BS/ing about McDonnell Douglas, the Harrier Air Craft and Charlie Plummer(chief test pilot) of the YAV8B. Truns out Shannon's sister married Charlie Plummer's son. SMALL WORLD! Two great guys in flight test were Ted Whitlow(foreman) and J.C. Thomas(general foreman) both these guys along with the test pilots were my heros at McDonnell Douglas. I retired from McDonnell Douglas Helicopters as a manufacturing engineer on the Apache/Longbow program in 1996 at age 55. Still living close to Boeing in Mesa, AZ and drive by the place often.

| Al Stenzel Manchester, MO | I was the Program Administrator for Logistics for the Harrier at McDonnell beginning in 1970. As for the Harrier Program, "I Have Been there, Done that!"
A few years ago the only remaining (of 2 built) YAV-8B Prototype airplane was sitting in the weeds with flat tyres at Spirit of St. Louis Airport on the North side next to our Civil Air Patrol's Meeting trailer. I knew it was a "Y" besause I helped build it! The airframe was an AV-8A Hawker Siddley built airplane "donated" by MAG 32 from MCAS Cherry Point, NC. McDonnell replaced the wing with a composite "supercritical airfoil" one and enlarged the engine inlets. Jack Jackson punched out of YAV-8B number 1 over the Ozarks while doing Engine Re-Start tests. (The engine didn't). I drove by Spirit Airport last week and YAV-8B 2 is no longer there. If someone out there knows where it is, please let me know!
