Abstract: An aircraft defining an upright orientation and an inverted orientation, a ground station; and a control system for remotely controlling the flight of the aircraft. The ground station has an auto-land function that causes the aircraft to invert, stall, and controllably land in the inverted orientation to protect a payload and a rudder extending down from the aircraft. In the upright orientation, the ground station depicts the view from a first aircraft camera. When switching to the inverted orientation: (1) the ground station depicts the view from a second aircraft camera, (2) the aircraft switches the colors of red and green wing lights, extends the ailerons to act as inverted flaps, and (3) the control system adapts a ground station controller for the inverted orientation. The aircraft landing gear is an expanded polypropylene pad located above the wing when the aircraft is in the upright orientation.

Abstract: A method of insulating a building having a foundation wall disposed at least partially below grade includes substantially covering the exterior surface of the foundation wall with panels of insulation material, securing the panels thereto with flanged retaining members interposed between adjacent edges of adjacent panels. The retaining members are secured to the foundation wall with the flanges thereof partially overlying the adjacent panels. The top edge of the insulation material is then covered to prevent the impingement of water and foreign matter onto the top edge and between the panels and foundation wall.A system for securing panels of insulation material to the exterior surface of a building foundation wall includes a plurality of flanged retaining members, each including a base portion and at least one flange laterally extended from the base portion to overly a panel in abutment with the base portion.
