Mission Boston - Mission Description

Mission Description

Boston was the second of two combat jumps, with "Mission Albany" preceding it by one hour to drop the 101st Airborne Division. Each mission consisted of three regiment-sized air landings. Drop Zones T and N were west of the Merderet River from north to south, and Drop Zone O was east of it, just northwest of Sainte Mère Église.

Each of its parachute infantry regiments (PIR) was transported by three or four "serials", formations containing 36, 45, or 54 C-47s, totalling ten serials and 369 aircraft. The planes, individually numbered within a serial by "chalk numbers" (literally numbers chalked on the airplanes to aid paratroopers in boarding the correct airplane), were organized into flights in trail, in a close pattern called "vee's of vee's" (3 planes in triangular vee's arranged in a larger vee of 9 planes). The serials were scheduled over the drop zones at 6-minute intervals. The paratroopers were organized into "sticks", a plane load of troops numbering 15-18 men.

The main combat assaults were preceded at each drop zone by three teams of pathfinders that arrived thirty minutes before the main assault to set up navigation aids, including Eureka radar transponder beacons and marker lights, to aid the C-47s in locating the DZs in the dark.

To achieve surprise, the parachute drops were routed to approach Normandy at low altitude from the west. The serials took off beginning at 2230 on June 5, assembled into formations, and flew southwest over the English Channel at 500 feet (150 m) MSL to remain below German radar coverage. Once over water all lights except formation lights were turned off, and these were reduced to their lowest practical intensity. At a stationary marker boat code-named "Hoboken" and carrying a Eureka beacon they made a left turn to the southeast and flew between the Channel Islands of Guernsey and Alderney to their initial point on the Cotentin coast near Les Pieux, code-named "Peoria".

Over the Cotentin Peninsula numerous factors negatively affected the accuracy of the drops, including a solid cloud bank over the entire western half of the 22-mile (35 km) wide peninsula at penetration altitude (1500 feet MSL), an opaque ground fog over many drop zones,and intense German antiaircraft fire ("flak"). The weather conditions broke up and dispersed many formations and the ground fire scattered them even more. However the primary factor limiting success of the paratroop units, because it magnified all the errors resulting from the above factors, was the decision to make a massive parachute drop at night.
