ABSTRACT:
A suspension cable for connecting together the carriage support ropes and the envelope load cords of a hot air balloon in the area of the burner assembly. The suspension cable comprises a non-electrically conductive material having a destruct point sufficiently high to avoid damage from the accidental exposure to the flame of the burner and a tensil strength sufficient to support the balloon carriage. The suspension cable is braided and the non-conductive material comprises an aramid fiber core. The suspension cable includes a non-electrically conductive sheath surrounding the core which will destruct if accidentally exposed to the flame of the burner in order to give an indication that the suspension cable should be inspected.
