Description: 1. Technical Field The present invention relates generally to protective shelters, and more particularly to redeployable aboveground shelters using valved ducting and/or retractable stabilizers to resist movement during high velocity wind events. 2. Description of the Related Art The construction of storm shelters, safe rooms and blast resistant modules is well known and thoroughly documented, for example, in FEMA 320, Third Edition and FEMA 361, Second Edition, both available from the Federal Emergency Management Agency(FEMA), as well as in ICC/NSSA 500: 2008 Standard for the Design and Construction of Storm Shelters, published jointly by the International Code Council (ICC) and the National Storm Shelter Association (NSSA) and in Section 6, Wind Loads, of MinimumDesign Loads for Buildings and Other Structures, SEI/ASCE 7-05, 2005, ISBN: 0-7844-0809-2, published by the American Society of Civil Engineers. To meet safety standards, conventional shelters require either burial below ground or, for abovegroundshelters, secure fastening of the shelter by numerous metal bolts or adhesives to heavy foundations or concrete "pads". For aboveground shelters, the combined weight of the shelter plus its foundation or "pad" is the primary factor relied upon to resistmovement of the shelter (and thus provide protection of its occupants) during high velocity wind events. In virtually all instances non-residential aboveground shelters are designed to be permanently installed at one location. The unavailability of redeployable protective shelters leaves at risk personnel that are temporarily located where severe wind events may occur. Those working on oil well drilling rigs, pipeline construction, wind turbine erection, petroleumrefineries, compressor station repair, and road construction and repair are examples of personnel at risk. One of the challenges of providing severe wind event protection for such personnel is the need for the shelter to be able to be easily, quickl
