REMARKS: CRASH CNFM - WE 938123 - NO SERCH -J

SYNOPSIS: The Lockheed P2 "Neptune" was originally designed for submarine
searching, using magnetic detection gear or accoustic buoys. Besides flying
maritime reconnaissance, the aircraft served as an experimental night attack
craft in the attempt to interdict the movement of enemy truck convoys.
Another model, the OP2E, dropped electronic sensors to detect truck
movements along the supply route through Laos known as the "Ho Chi Minh
Trail".

The Ho Chi Minh Trail was used by the North Vietnamese for transporting
weapons, supplies and troops. Hundreds of American pilots were shot down
trying to stop this communist traffic to South Vietnam. Fortunately, search
and rescue teams in Vietnam were extremely successful and the recovery rate
was high.

Still there were nearly 600 who were not rescued. Many of them went down
along the Ho Chi Minh Trail and the passes through the border mountains
between Laos and Vietnam. Many were alive on the ground and in radio contact
with search and rescue and other planes; some were known to have been
captured. Hanoi's communist allies in Laos, the Pathet Lao, publicly spoke
of American prisoners they held, but when peace agreements were negotiated,
Laos was not included, and not a single American was released that had been
held in Laos.

Delbert Olson was the pilot of an OP2E electronic observation aircraft
assigned to Observation Squadron 67 at Nakhon Phanom, Thailand. On January
11, 1968, he and a crew of eight, including Denis Anderson, were dispatched
on an armed reconnaissance mission over Laos. The aircraft lost radio and
radar contact at 9:57 a.m. When the plane failed to return within a
reasonable time, an extensive visual, electronic and photographic search was
conducted in the area of the aircraft's last known position.

On January 23, a USAF A1 located a suspected crash site. On January 25th an
O2 from the 23rd Tactical Air Support Squadron photographed the site. Using
the photographs for photo interpretation, and in conjunction with visual air
reconnaissance of the site, it was determined that the wreckage was that of
Commander Olson's aircraft. The aircraft crashed on the northern side of a
sheer cliff, 150 feet below the 4583 foot summit line, about 15 kilometers
northeast of Ban Nalouangnua, Khammouane Province, Laos. It was decided that
all indications were that there were no survivors and most probably no
identifiable remains. Because of the heavy jungle canopy, irregular terrain
and the close proximity of enemy forces, no ground team was inserted to
inspect the crash site for remains. There was no indication as to the exact
cause of the crash.

All members of the crew were placed in an initial casualty status of Missing
In Action. On February 23, 1968, the crew was placed in a casualty status of
Presumed Killed in Action/Body Not Recovered.

The crew of the OP2E lost on January 11, 1968 are among nearly 600 Americans
lost in Laos. Because Laos was not a party to the agreements ending the war,
no Americans held by Laos were ever released. Since the war ended, nearly
10,000 reports have convinced many experts that hundreds of Americans are
still being held captive in Southeast Asia. While the crew of the OP2E may
not be among them, one can imagine them proudly flying one more mission to
bring home the evidence needed to bring them to freedom.
