Abstract: A system is disclosed whereby a sensor, communication device, or other payload may be lofted to an operational altitude and maintained over an area of interest for some time by a relatively inexpensive and disposable buoyant aircraft, then returned intact to its point of origin or another desired location by a reusable but also relatively inexpensive non-buoyant aircraft. Automatic unpiloted control is used for all stages of flight, including ascent, loiter, return, and landing Specialized equipment can be provided to simplify launch procedures, reducing the number of personnel required to operate the system.

Abstract: A game and method of play are disclosed. The game consists of a playing field and at least two groups of playing markers, the groups being distinguishable from one another. Each playing marker has memory indicia thereon to mnemonically signify a continuous, sequential order by which the markers are moved. Players move their markers around the playing field one at a time, adhering to the order described above. A player cannot deviate from the specified order, and must move a marker with each turn. The object of the game is for one player to arrange his markers in a line on the playing field while preventing an opponent from doing so. Points are awarded when a player arranges his markers in a line.
