Each drone carried two filter units; one on the top of the fuselage just back of the pilot's seat, and one on the bottom of the fuselage just under the nose of the plane, The units were fastened to the planes by dowel pins which could be released by pulling lanyards attached to the pins. Ech lanyard ran from its filter unit to a point just back of the wing. The handle of the lanyard wes held at this point in a holder attached to the fuselage of the plane. A special lift arrangement vas cerried by truck from plane to plans to lift the top filter unit. When this special lift was in position, ons radiochemist would epproach the plane, detach the lanyart handle from its holder and release the filter unit by pulling on the lanyard. The special lift would then carry the filter mit to a point about fifty feet from the Plane where two radiochenists transferred the filter unit (by hand) from the special lift to the ground. The bottom filter unit was allowed to fall to the ground when its lanyard was pulled. It was then dreggeid along the ground by the lanyard to a point about fifty feet from the plans.

Each side section was fastened to the filter unit by eleven pins which vere in turn held in position by wires running through holes in the pins. These vires vere all attached on ons handle so that ones pull on the handle released the entire side sectian. The detached paper holder was then carried away from the main body of the filter wit.
