In the "Skunk Works" book they explain that you could throw a lit cigarette directly into a puddle of fuel and it would not ignite, due to the very high temps needed.
Yes but for a different reason - car gas because it's the vapors which ignite, so if you toss a cigarette on a fresh puddle of car gas you're going to have a very bad day. For planes it's due to the much higher temperatures required, the worst thing you'll do tossing a cigarette into a fresh puddle of jet fuel is burn your finger.
