Last Known Activity

On 29 December 1967,  Maj. Charles P. Claxton, aircraft commander; then Capt. Gerald G. Van Buren, 1st pilot; Capt. Edwin N. Osborne Jr., pilot; Lt. Col. Donald E. Fisher, navigator; Capt. Frank C. Parker III, navigator; Capt. Gordon J. Wenaas, navigator; SSgt. Gean P. Clapper, radio operator; SSgt. Wayne A. Eckley, flight engineer; TSgt. Jack McCrary, flight engineer; SSgt. Edward J. Darcy, loadmaster; and Sgt. James R. Williams, loadmaster; comprised the crew of a C130E (tail number 64-0547). The aircraft departed Nha Trang Airbase, South Vietnam at 0030 hours on a highly classified special mission over the rugged jungle-covered mountains of Tuan Giao District, Lai Chau Province, North Vietnam.


0430 hours, the pilot made radio contact with the Nha Trang air traffic control tower reporting the mission was progressing as scheduled. When no further radio contact could be established with the aircraft or its crew, and it failed to return to base at the time its fuel supply was exhausted, search and rescue (SAR) efforts were organized. The last radio transmission with the C130E placed the Herc over a region that was sparsely populated approximately 7 miles south of Ban Nam Muong, 19 miles southwest of Ban Ko La, 28 miles southwest of the Vietnamese/Chinese border and 41 miles northeast of the Vietnamese/Lao border. Over the next two weeks 1 electronic search and 3 photo reconnaissance missions were conducted over these extremely rugged enemy controlled mountains of northwestern North Vietnam. When no trace of the aircraft or crew was found, the formal search was terminated on 29 January 1968. At that time all eleven crewmen were listed Missing in Action.  

On 8 June 1994, a Vietnamese citizen turned over an unspecified number of bone fragments to JTFFA's Detachment 2 in Hanoi and reported that another resident of Son La Province had remains and material evidence belonging to men aboard this C130E. Later that month JTFFA team members traveled to Son La Province to investigate this report further. At that time they received some remains, but believed the villager(s) had chosen to hold either remains and/or material evidence back from those they considered outsiders. The Vietnamese Border Defense Forces representative agreed to continue the investigation noting that "local people considered US and Central Vietnamese outsiders." According to the JTFFA site report, the remains recovered by the Son La People's Committee were repatriated to US control on 13 February 1995.


By August 1997, the search for the crewmen of the C130E took another unusual turn. Another Vietnamese presented Detachment 2 with a rubbing of a military dogtag for Col. Fisher. She said some close friends are holding identification tags and a skull at their home. She said she would return to their homes and encourage the friends to turn in the remains. She also told them she repeatedly dreamed she would meet a man with American remains who would ask for her help. She went on to say the man approached her on a Hanoi street and gave her a dogtag rubbing, then asked her to take it to Detachment 2. She said she did not know the man's name, and he never contacted her again.


In January 1998, yet another Vietnamese reported to Detachment 2 that a relative found remains and an ID tag in Tuan Chau District. He said he was holding other remains associated with this incident. As proof he presented them with a computer-printed replica of Col. Fisher's dogtag and a ½ inch bone fragment. He said he had the real dogtag and a full set of remains. Upon examination by the Central Identification Laboratory, Hawaii (CIL-HI), the bone fragment was determined to be Mongoloid.


Six months later, in June 1998, the same Vietnamese who made the January report adjusted it. He said he went to a wedding in Thuan Chau Village, and his nephew told him local residents had the remains of an American soldier. His nephew took him to another village where he was shown several large pieces of bone. He thought they were American due to their size and the presence of an identification tag. These people told him they bought the remains from an ethnic Hmong. When queried about the man and village, he said he could not remember the name or the village and could not contact his nephew by telephone.


The remains turned over by the Vietnamese were combined with the remains recovered during the crash site excavation, which was closed on 13 December 1993. All the remains were transported to CIL-HI for examination. Of the 11 men on board the C130E, both dental and mt-DNA were used to positively identify Edward Darcy, Wayne Eckley and James Williams. Frank Parker and Donald Fisher were positively identified by mt-DNA only. According to CIL-HI analysis, no individual association could be made between hundreds of fragments and specific crewmen. The fragments were fractured in a manner consistent with an aircraft crash and were all in a similar state of preservation. Consequently, these individually unidentifiable remains were grouped as remains "from an incident involving" 11 men. While CIL-HI made this determination for the entire crew on 9 March 2000, the announcement was not made public until the US Air Force had the opportunity to contact all of the crewmen's families. All remains were turned over for burial on 6 November 2000. On 15 November 2000, these remains were interred in a group burial in one casket in Arlington National Cemetery under a headstone bearing all 11 crewmen's names.

The families of Charles P. Claxon, Gerald G. Van Burin, Edwin N. Observe Jr., Donald E. Fisher, Frank C. Parker III, Gordon J. Weans, Jean P. Clapper, Wayne A. Beckley, Jack McCrary, Edward J. Dray, and James R. Williams finally have the peace of mind and know within reason where their loved ones are buried. For other Americans who remain unaccounted for in Southeast Asia, their fate could be quite different...

"Hello, Mike: For what it's worth, while scanning this site tonight, I recall CMSgt (then SSgt) Gene P Clapper was assigned with me at our old organization, 20th Field Maintenance Squadron, RAF Wethersfield, Essex, England. If I'm not mistaken, he was assigned to the Base Flight Section. I was there 1963-6 and he was there until around 1965...I recall because he was the first person I knew who was going to Viet Nam. Maybe my aging prevented me from remembering him until his name appeared suddenly.... it is a memorable name....I actually endorsed his Airman Performance Reports (APRs) for the Squadron Commander, Captain Franklin A Teat..."
