Narrative:
The MAG-16 Command Chronology for 8 Jan reads: "At 19:15 Hours one HMH-463 CH-53A (YH-37 Bureau Number 153710) was declared overdue and missing after disappearing during an IFR flight.
Search and rescue operations commenced."

On the 9th and 10th, "The search for the missing CH-53A aircraft continued with negative sightings and search operations hampered by inclement weather." On the 11th, "The wreckage of the missing CH-53A aircraft was sighted by search aircraft at coord. YD234260, no apparent survivors.

Adverse weather conditions precluded a search of the crash site until 19 Jan when a recon team was inserted. The aircraft suffered severe burn damage and there was no possibility of survivors." In the casualties (hostile) section, the names of the five crew members are listed and the place is described at 18 miles S Dong Ha, RVN

43 of those KiA are interred at the Jefferson Barracks National Cemetery, St Louis, MO : Plot 81 0 270-272. Burial date is listed as July 23, 1968. This is believed to be, still the greatest loss of life in a single incident for a helicopter worldwide to date.
