Wikimedia Commons has media related to Aircraft with pusher-propellers.

This category is for aircraft constructed with a pusher configuration, where the engine is mounted with the propeller facing to the rear of the plane, such that the aircraft is "pushed" through the air, as opposed to the tractor configuration in which the aircraft is "pulled" through the air.

This category does not apply to aircraft with non-propeller based propulsion systems, such as jet engines, even though these may also be rear facing.
