    摘要： There are provided foamable, foamable polyvinyl halide resin masses containing: A) 1 to 25 parts relative to 100 parts of polyvinyl halide, of a polymerizate obtainable through the emulsion polymerization of i) up to 20 to not more than 75 parts of methylmethacrylate, ii) 25 to 80 parts of one or more C.sub.2 -C.sub.18 alkylmethacrylates, iii) 0 to 5 parts of one or more vinyl unsaturated monomers copolymerizable with (i) and/or (ii, wherein the components (i)-(iii) together yield 100 parts and are polymerized with up to a further 100 parts of usual additives for emulsion polymerization, wherein the emulsion polymerizate is single stepped and has a viscosity number of >700 cm.sup.3 /g and wherein copolymers are excluded which contain iv) MMA per se, or less than 20 or more than 75 parts of MMA together with either v) one or more acrylic acid esters, and/or vi) ethyl methacrylate, n-butyl-methacrylate, or ethylhexyl methacrylate. The resin mass further includes: B) 0.1-10 parts based on 100 parts of the polyvinyl halide of one or more foaming materials, C) 0-100 parts based on 100 parts polyvinyl halide of the usual additives. This polyvinyl halide resin mass, after foaming, yields a resin mass which, as well as of good surface properties, has a foam density of

    摘要： 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.
