I understand the point, and I know a shoulder fired manpad didn’t have the slant range to take down TWA800 unless it was perfectly in flight path, yet if there was a genuine fuel tank error with a shorted pump, why weren’t all 747’s GROUNDED to repair the prblem ??
That’s a good question. In fact I have heard that while they weren’t grounded, the wiring in ALL Boeings was hastily re-routed, and it was a pretty big issue at the time.
