Unmanned aircraft systems with a customer interface system and methods of delivery utilizing unmanned aircraft systems

An unmanned aircraft system (UAS), comprising:

• a crane system comprising a first spool system and a crane motor cooperated with the first spool system, wherein the first spool system comprises a first cord that is extended and retracted in response to the crane motor driving the first spool;
• a physical retractable interface system secured with and cooperated with the first cord;
• a package holder configured to hold a first package to be delivered by the UAS at a delivery location;
• a control circuit coupled with the crane motor to control the crane motor;
• and
• a memory coupled to the control circuit and storing computer instructions that when executed by the control circuit cause the control circuit to perform the steps of:
• activate the crane motor to extend the first cord and lower the retractable interface system while the UAS is maintained in flight at least at a threshold height;
• wherein the retractable interface system comprises an input interface comprising a payment method system, a physical display and user selectable options configured to receive physical input from a customer at the delivery location when the retractable interface system is lowered and accessible to the customer while the UAS is maintained in flight, and wherein the retractable interface system further comprises a wireless communication interface and an interface system control circuit configured to control the payment method system to obtain payment information and cause the acquired payment information to be wirelessly communicated via the wireless communication interface to a remote payment system.
