The invention relates to an electron gun triode for a cathode ray tube in which the cathode has a projecting emissive zone, centred on the Z-axis of the gun and which advances toward the first electrode. The vehicle further includes a processor configured to monitor for an operator presence in the first operator position or the second operator position and receive a vehicle operating request, wherein the operator presence is monitored independent of receiving the vehicle operating request. 05% to about 10% by weight of a rheology modifying fabric softening active comprising at least one long chain amine of the present technology, a derivative thereof, or a mixture thereof, and from about 1% to 10% by weight of an additional fabric softening active dispersed in water. The porous film having the higher tensile strength has smaller holes andor is thicker than the other porous film. The torpedo is constructed with a size and weight that enables it to be carried by and launched from an unmanned aerial vehicle.
