Actually, the L1011
does use Kapton, but the wiring harnesses are better designed than those on other aircraft - especially McDonnell Douglas and Boeing.
Boeing now uses TKT - a sandwich of Teflon Kapton and Teflon - in its aircraft (though it does still use Kapton in "accessible" areas); whereas Airbus still use Kapton throughout their aircraft.
It's highly probable that as well as SR111, Kapton wire arc-tracking may well have caused the crash of SAA's Boeing 747 Combi
Helderberg off Mauritius in November 1987.
