Clay Moore's reasoning is sound. Especially when you compare the 45,000 flights a day to 1.1 BILLION car trips per day in the USA.
If you'd like another example, pour out an orange sized puddle of diesel fuel or kerosene on the hottest sidewalk you can find this afternoon. Give it a moment and try to light it with a match. It isn't easy.
The NTSB literally recreated the exact conditions in another CWT, and it exploded.
Again, just because something doesn’t happen frequently doesn’t mean it can’t happen at all.
Oh and ever compare the temperature of a match to an electrical arc? Like, do you think the match is burning as hot as plasma?
The both of you should look up Thai Airways 114.
