178th Assault Support Helicopter Company (callsign Boxcars) CH-47 helicopter
(CD Version)

The CH-47B Chinook helicopter was a twin-engine, tandem rotor, medium transport helicopter
with fixed four-wheel landing gear.  It had a normal crew of three, with a crew chief.  A cargo
winch had a 3,000 lb. capacity.  The rear loading ramp permitted straight-in loading and a sealed
hull gave the aircraft an emergency water landing capability.  It could carry 33 combat-equipped
troops at 110 knots cruising speed.  The external sling capacity was 16,000 lbs.  With a flight
endurance of 2 hrs 40 min, the aircraft could move over 15,000 lbs. in a 50 nautical mile radius.

Soldiers in the 1st Battalion 6th Infantry sometimes were moved by these large CH-47 aircraft
between firebases and from field locations back to a firebase or to Chu Lai.  Only rarely were these
aircraft used to move troops to the field when the security of an LZ could be questionable.

On 26 Aug 70, 22 soldiers (from D Co. 2nd Bn 1st Inf, 196th Inf Bde) and the crew of 4 (from
178th ASHC) were killed when bursts of  AK-47 rifle fire struck the unfortunate Boxcar aircraft
as it was on a final approach into LZ Judy, far to the northwest of Chu Lai.  Only one soldier survived
the crash.  Thereafter, commanders were understandably reluctant to use the CH-47s to move troops
when the PZ or LZ could be covered by the VC.  Some pilots loved the aircraft--others swore that
it was inherently unsafe and that they would never ride in one whether or not they were at the controls.

Soldiers from B Co, 1st Bn 6th Inf, load onto a CH-47 helicopter from the 178th ASHC at LZ Dottie
preparing to move to Hill 43 (east of LZ Dottie) in September 1970.  Note the gear strapped on the
rucksack (keeping in mind that this is only what is visible in this photograph on the outside of the pack):
 4 canteens; two bandoleers of M-16 ammunition (14 magazines); 1 box M-60 ammo;  one clamor
bag; one smoke grenade; and, one poncho.  Additional items inside the rucksack probably include an
additional bandoleer of M-16 ammo in clips rather than magazines; more ammo in a box for the M-60;
trip flares; and, hand pop illumination flares.  When fully loaded with ammunition, food, and water, the
rucksack could easily weigh sixty or seventy pounds.

[Note:  this CH47B Boeing Serial No. 67-18465, Boeing Mfg #B-435 survived the war and was
remanufactured into a "D" Model 88-00090.]

Soldiers from B Co. 1st Bn 6th Infantry unload at Hill 43 (BS 685 917) from CH-47 helicopters from
the 178th Assault Support Helicopter Company (Boxcars).  Note the double six dice painted on the aft
of the aircraft.

A CH47 Chinook helicopter drops off a load at an LZ in 1970.  The rotor wash produced tremendous
winds on the LZ/PZ that could knock a man down if he stood upright without bracing himself.  A small
LZ/PZ sometimes was left in shambles as boxes, tents, etc. were blown away when the aircraft departed.

you step! See CH-47 interior at this link.  (The hedge rows visible on the ground provide good
concealment for trenches and bunkers.  Helicopters are interesting, but the stuff on the ground
could kill you!)  Photo from Ray Mendez (3/B/1-6 Inf 1970-71)
