We had reports of some....never saw any.
The Snoul airstrip was really pretty....pretty green sod...wide...long...well marked. There were two French built light airplanes there when I showed up looking for my customers. I elected to leg it when I realized my Chinook made an enticing target.
The scary part is the NVA had lots of .51 AAA sites along the treeline down the runway and were in the area in mass as evidenced by the big shoot-out that occurred when the 11th Armored Cavalary finally showed up the next day.
Why the NVA let me get away will always be one of the unanswered questions of my life! We were all alone....no friendly troops on the ground....it describes the fire discipline of the NVA.....definitely good troops.
