The invention provides a quickly deployable fabric cover over rectangular containers to protect contents from stationary or mobile activities. Operated by a single person to secure or unsecure the cover and to cover or uncover the container minimizes time and energy to protect container contents from inclement weather events or transportation.

A tank assembly for a helicopter is provided. The tank assembly includes a retractable tank for storing liquid or other substances. The retractable tank includes an upper frame structure. The tank assembly further includes an attachment mechanism attached to the upper frame structure and configured to engage a main rotor transmission of the helicopter to suspend therefrom. A helicopter including a fuselage, a main rotor transmission, and a tank assembly is also provided.
