| Scott Humes Florissant, MO | I was a Radar technician on the Ec121d/t model and had 8, 5 month long TDY's to SE Asia in 1967,68,69,70,71,72,73&74. When not in SE Asia we were sent to Iceland, Family Man (protecting the President)worked with NASA during the early days of Mercury, Gemini, and Apollo. I have very fond memories of the "connie" as it saved my rear many times. IT didn't always have all its engines turning but I'm here to say I'm proud to have flown her. I moved on to the E-3A 1978-1982, Nato AWACS at Force command!982-1986, and back to E-3a 1986-1989 06/15/2015 @ 11:33 [ref: 69130] |

| Larry Westin - westin@tdstelme.net Newport, ME | This is in reference to James Lawson question, reference 25988. The Da Nang Glider you refer to is EC-121R serial number 67-21487. The unit was the 553rd Reconnaissance Wing, code name Batcat. Please contact me for further information, you can do a Google search for "Batcat" or "Da Nang Glider." I have details of the incident on my Batcat homepage, along with Veterans information about the use of herbicides at Korat RTAFB. 01/21/2011 @ 05:30 [ref: 35834] |

| Miranda Littleton, CO | My father, Allen Henke, flew as radio operator on 555. He flew around 1956-57 when I was born in Sacarmento, CA. I'm wondering if there is anyone out there that can tell me about those experiences or knew him. Intersting note, he met my mother by putting out a fire in her car with a chocolate malt at a stop light. He could tell a joke for any occasion and I miss him.
Thanks, Miranda 10/06/2010 @ 02:01 [ref: 31129] |
| CMSgt Ken Witkin, USAF (Ret.) Fort Washington, MD | From October 1963 to July 1966 I was assigned to the 964th AEW&C Squadron, McClellan AFB, California as an airborne radio operator. We flew 14-hour Active Air Defense (AAD) missions about 150 miles off the West Coast of the United States. There were five West Coast orbits and so we had five EC-121D aircraft airborne 24/7. There were three flying squadron and each squadron had a squadron communications section of about 20 airborne radio operators (A292X2). The 964th AEW&C Squadron NCOIC of Communications was MSgt Popham. Our squadron commander was Lt Col Sam Tidwell and my aircraft commander was Captain Albert Mitchell. In January 1965 I was sent TDY to Tan Son Nhut AB, South Vietnam to take part in a classified project and I remained in South Vietnam until May 1965 when I returned to McClellan AFB. While in Vietnam I had the opportunity to greet the first College Eye EC-121D aircrew to land in Southeast Asia. One of my former aircraft commanders was on that first College Eye aircraft. Boy, was he ever surprised to see me when I came on board at Tan Son Nhut. The first words out of his mouth were: “What the hell are you doing here?” :=) 05/17/2010 @ 14:19 [ref: 26184] |
| James Lawson Yuma, AZ | I am trying to help my cousin Ronald Donley with a VA claim. Ron was sent to Da Nang from Korat TDY to assist in the engine repair of the EC-121 that lost all four engines in flight, Nick named the Da Nang Glider. The VA is saying he never went to Vietnam, I am looking for anyone that knew Ron that knew he did indeed go to Da Nang. The Air Force says they have no records, Travel or Pay, amazing right. Please if anyone can help drop me an email and let me know, Thank You Very Much, 04/07/2010 @ 01:47 [ref: 25988] |
| M.D. Newell Fort Walton Beach, FL | Looking for anybody that flew with my father, Lt Col Don Newell, who was a pilot on the EC-121. He was in Korat, Thailand during '68-'69. Have a picture of a Thai gardner watering an aluminum Christmas tree outside the BOQ. Lt. Col Lyle and Maj Sutton come to mind. Thanks!....M. Newell 03/31/2010 @ 11:32 [ref: 25957] |
