Mid Air Collision at Camp Evans
October 3, 1968


Probably one of the greatest fears in Vietnam was to die on the way home. Time and again there were example after example of how you weren't really safe until you heard the wheels thump into the wheel wells of the DC-8 Freedom Bird taking us home. What follows is our recollections of that day in 1968, the accident report and the list of all known KIAs from the National Archives for the First Cavalry Division. It all started with:

Official Accident Summary:

THE US AIR FORCE C7-A DEPARTED CAMP EVANS AIRFIELD FROM RUNWAY 36. HIS LAST RADIO TRANSMISSION AFTER RECEIVING TOWER CLEARANCE WAS "ROLLING". THIS AIRCRAFT WAS OBSERVED TO BREAK RIGHT PRIOR TO REACHING THE END OF THE RUNWAY. HE CONTINUED A CLIMBING TURN TO A HEADING OF APPROXIMATELY 130 DEGREES. THE CH-47 HELICOPTER HAD DEPARTED LZ NANCY ONLY A FEW MINUTES BEFORE.

IT WAS PROCEEDING SOUTH ALONG HIGHWAY QL-1, ON A HEADING OF 170 DEGREES, IN A SHALLOW DESCENT. THIS IS A SCHEDULED DAILY PASSENGER AND MAIL SHUTTLE AND WOULD HAVE ENTERED TRAFFIC ON A RIGHT BASE LEG FOR LANDING AT THE CAMP EVANS ASP PAD IS THE REGULAR STOP FOR THIS SHUTTLE AND IS LOCATED EAST OF THE CENTERLINE OF RUNWAY 36, APPROXIMATELY 1000 FEET SOUTH OF THE APPROACH END OF THAT RUNWAY.

HE HAD NOT YET CALLED THE TOWER FOR CLEARANCE, THOUGH HIS UHF RADIO WAS ON TOWER FREQUENCY. IT IS ESTIMATED THAT THE CH-47 WAS CRUISING AT APPROXIMATELY 95 TO 100 KNOTS. THE C7A WITH CLIMB POWER, SHOULD HAVE BEEN AT ABOUT 105 KNOTS. THE TWO AIRCRAFT CONVERGED AT AN ALTITUDE OF APPROXIMATELY 1100 FEET AT A RELATIVE ANGLE OF APPROXIMATELY 40 DEGREES. THE COCKPIT SECTION OF THE C7-A CONTACTED THE REAR ROTOR OF THE HELICOPTER. THE C7-A HAD STARTED A RIGHT BANK, PROBABLY A LAST MINUTE ATTEMPT TO AVOID THE COLLISION. WHEN THE TWO AIRCRAFT COLLIDED, AT LEAST ONE OF THE HELICOPTER REAR ROTOR BLADES SLICED THROUGH THE COCKPIT SECTION OF THE AIRPLANE ON AN ANGLE FROM THE TOP OF THE COPILOTS WINDSHIELD DOWN TO THE BOTTOM OF THE PILOTS WINDSHIELD, KILLING BOTH PILOTS INSTANTLY, AND DESTROYING ALL ENGINE CONTROLS.

AT THE SAME TIME, ONE OF THE ROTOR BLADES, OR DEBRIS FROM THE COCKPIT STRUCK THE LEFT PROPELLER OF THE C7-A. ONE OF THE BLADES WAS SEVERED FROM THE PROPELLER, AND PASSED THROUGH BOTH SIDES OF THE FUSELAGE OF THE AIRPLANE. THE LEFT PROPELLER THEN SEPARATED FROM THE ENGINE AND FELL TO THE GROUND. THE C7-A MADE A STEEP DESCENDING RIGHT TURN AND STRUCK THE GROUND ON A HEADING OF 340 DEGREES. THE AIRCRAFT DISINTEGRATED, ALL PERSONNEL ABOARD PERISHED, THERE WAS NO FIRE. THE CH-47, AT THE MOMENT OF THE COLLISION LOST ALL OF ITS REAR MAIN ROTOR BLADES. ONCE THESE BLADES WERE BROKEN AND DISTORTED BY THE COLLISION, THEY CHOPPED INTO THE TOP OF THE HELICOPTERS FUSELAGE BEFORE FINALLY SEPARATING FROM THE HUB.

THEY DISLODGED TWO SECTIONS OF THE SYNCHRONIZER DRIVE SHAFT WHICH ALSO FELL TO THE GROUND. AT THIS TIME, NEITHER ROTOR SYSTEM COULD PROVIDE ANY THRUST, AND THE HELICOPTER BECAME A FREE FALLING BODY. WHILE IT WAS TUMBLING TO EARTH, THE REAR ROTOR MAST AND PYLON SEPARATED FROM THE FUSELAGE AND LANDED 150 METERS SHORT OF THE FUSELAGE. THE FUSELAGE TUMBLED TO EARTH AND IMPACTED ON A HEADING OF APPROXIMATELY 120 DEGREES. IT LANDED ON ITS TOP LEFT SIDE IN A NOSE HIGH ATTITUDE, WITH NEAR ZERO FORWARD SPEED. IT EXPLODED ON IMPACT. TWO PERSONS FELL OUT OF THE HELICOPTER AS IT TUMBLED THROUGH THE AIR. THEY WERE FATALLY INJURED ON CONTACT WITH THE GROUND. THOSE REMAINING IN THE HELICOPTER DIED IN THE CRASH.

From the United States Air Force in Southeast Asia-Tactical Airlift, page 475:
Prior to 1968, three serious operational problems defied effective solution, all requiring better coordination between the U.S. Army and the Air Force in the field. First, flying officers of both services testified to the danger of midair collision near forward airstrips. This was the result of uncontrolled flying, incompatible radio equipment, and the absence of commonly accepted procedures for Army helicopter and Air Force transport operations at shared airfields. A midair collision between a Caribou and a Chinook near Camp Evans on October 3, 1968, cost twenty five lives and tragically illustrated the problem. Second, physical conditions at forward airstrips were sometimes unnecessarily dangerous. Hazards included bunkers or other obstacles near runways and taxi areas, uncontrolled vehicle and pedestrian traffic and landing surfaces needing improvement. Third, a better system for warning transport crews of firing by friendly artillery was needed.


Joe Potvin A/227 a UH-1H Huey unit

I was sitting in POL hot refueling and watched the C7-A take off to the North from the active runway. We were facing north so I lost sight of the fixed wing after it made a hard right break which I'm sure kept it either inside of or over Hwy 1. The Air Force jocks thought the Evans area was pretty dangerous so they max performance takeoffs out of there to limit exposure.

The next thing I knew was my crew chief was at my door telling me he had just watched the C7 run into a Chinook, at about the same time the tower frequency lit up with calls for assistance from any helicopters in the area.

We buttoned up and headed for the crash sight, you could see smoke coming from the CH-47 crash site but the C7 was harder to find. I landed next to the C7 wreckage ( a polite term meaning big ass hole in the rice paddy ) and did a quick walk around with my crew chief. There wasn't a thing left. It was all buried in the rice paddy ( no standing water but still wet ). The biggest thing I saw was one of the mangled engines..

Chief and I looked at each other, went back to aircraft and left the area. Not a pleasant sight. By that time many more troops were arriving and it was clear we were only in the way. I don't think any of us wanted to stay around and sift through the wreckage looking for parts.


Gene Lassiter, 228th, 68-69

I was already at Bn HQ when this happened. I remember Lt. Col. Paquette , who commanded from June to December 1968, in a rage because the AF type who commanded the Caribou unit tried to blame the Hook for the crash. It turned out that the Caribou driver was horsing around and pulled a steep climb and turn immediately after take-off. If I remember right, the blade of the Hook took out the cockpit of the Caribou and it was thought that the plane was otherwise flyable, but of course had no hands "at the wheel". I think there was a Longhorn on the Caribou going on R&R; and his brother was at Evans watching the whole thing. I could be wrong about that. Still don't remember the date. The 228th flight surgeon was one of the first on the scene and I'll never forget his face when he came back. We were all pretty sick.

Dave Greene B/227th

The mid-air between the hook and the caribou happened the day before I was to DEROS (from Evans to An Khe). I was watching the Caribou take off ('cause I was to ride it the next afternoon), when it turned through the downwind leg of traffic. It clipped the back rotor of the hook. It lost about 15-20 feet of wing, but the rotors probably went through the cockpit too. It pitched up to stall, then nosed over straight down. The hook started to spin, throwing bodies out the back of the aircraft. God, what a horrible sight. I think 42 people were killed. It was hard to get on that plane the next day!
