An aircraft crash sensor activates an aircrew safety device upon sensing an aircraft impact in any direction to minimize the aircrew flail envelope and reduce the possibility of injury caused by the crash. The generator is of the kind being directly coupled to the main shaft of the wind rotor of the windmill. The conductive surface is disposed at a quarter wavelength spacing from the existing antenna.
