The MC1-1 parachute, commonly called the Dash 1, is the U.S. military's static line deployed steerable troop parachute. Currently, there are two versions, the MC1-1B and the MC1-1C, in service. The Dash 1 is used less often than its non-steerable counterpart, the T-10C, because its forward motion and steerability increase the chance of mid-air collisions between jumpers. It is similar in size, shape and weight to the T-10C, and both the parachutes utilize the same pack tray, static line/D-bag, and harness assembly. The steerability of the Dash 1 is achieved through the removal of several panels at the rear of the canopy, which provides a forward drive of about 9 miles per hour. The parachutist can turn by pulling on toggles which attach to two control lines. The control lines change the shape of the opening and allow turns to the left or right.
