A flexible transparent door is provided for attachment to the entry opening of a helicopter or other vehicle. This door has a semi-permanent attachment effected by means of Velcro or any comparable hook and pile material distributed about the outer periphery of the door and secondarily held by means of accordion rivets. Hinges are also provided at this outer periphery for insertion into a slide mount permanently affixed to the helicopter. A zipper is provided spaced from the outer periphery and in circumferential relation to a clear vinyl window provided on the door. In normal use, the zipper is actuated to open the door for ingress and egress. In emergency situations, quick removal of the door from the body of the vehicle may be effected by separation of the Velcro and accordion rivets which bind the door to the vehicle. In this manner, the entire door will pivot upon the hinge provided and an emergency exit will be available.
