A hydroplaning hydrofoil and airfoil planing or flying wing structure is disclosed based on the concept of forward-swept planes or planar surfaces having swept-back fore foil sections and forward-swept aft foil sections upon which the hydrofoil/airfoil structure optionally supports itself and planes on or through a fluid preferably either water or air. Also disclosed are aquatic structures or watercraft to which the hydroplaning hydrofoil/airfoil structures are optionally attached. In addition, light weight amphibious structures are disclosed; preferably these structures are sail, engine, or electric motor powered craft to which the hydroplaning hydrofoil/airfoil structures are optionally attached.
See-through, hand-held, bullet-resistant shields are disclosed which provide life-saving upper body protection for a police officer, shopkeeper, bank teller or any person holding said shield, or standing or ducking behind said shield when substantially vertically mounted on the side of a counter top surface. Such shields are formed from a totally see-through or substantially transparent (no lens) bullet-resistant sheet material, capable of being vertically disposed and of a size and shape so as to provide upper body frontal protection of at least a person's face, head, neck, forearm, hand and upper chest anatomy; and has at least one hand-gripping means centrally attached to and spaced from one side of said transparent sheet.
