The original batch of Jetstars including LBJ's VC-140 had severe wiring problems "Wet Wie Fies" was the term used. Some poor wiring installations at GLAC left damaged insulation especially around wire bundle (looms) clamps. In the presence of moisture the coppers would dissolve and literally plate itself, not something wanted. to ground. This formed a thin film heater, something you didn't want.
LASI NY stripped the interiors and completely rewired the affected aircraft. On LBJ's aircraft we did not reinstall the regular interior. LBJ hadn't liked it so it ferried to Texas, I think to Horton and Horton.
I was the Production Controller on LBJ's aircraft assigning work to Crew Chiefs. A lot of manhours expended. Glad to see that the old bird is till around and looks as pristine as back in the 1960's as part of SAMFLEET.
Lockheed loved rubber deicer boots for some reason. Of course, the wing was small and thin and running pneumatic air through the leading edges would have taken space.
