 One of the most interesting subtle issues was the surely well intentioned 
use of 
 silver plated crimp connectors in the FQIS. Turns out that after a few 
decades, 
 the sulphur in the fuel has combined sufficiently with the silver on the 
 connector to form a semi-conductive silver sulphide film on terminal 
blocks, 
 capable of providing an ignition source if sufficient voltage is applied. 
 
That ignition source relies on the 140 Ampres of three phase under the 
flight deck floor of TWA-800. (ie upper deck alley)  The best that can be 
said for TWA-800 is that the market punished the perpitrators perfectly.
