Abstract: A method, device, and system for rotary wing aircraft for the purpose of rescuing trapped or injured people from vertical surfaces and structures, and transferring individuals or objects at vertical surfaces generally. The device consists of a containment structure, boom, counterweight, attachment point, and cockpit controls. The device is quickly attached to specially modified and equipped rotary wing aircraft, and placed in service to rescue people trapped in a high-rise building due to fire or other hazard and to rescue trapped or injured hikers and climbers from steep mountainous terrain or vertical rock surfaces. Applications include depositing personnel onto a vertical surface or the upper reaches of a vertical structure.
