*LOL*
My post to your question was merely an untested theory -- or guess for lack of a better word.
DoomSlayer can speak better of the Napalm Effects -- as he made them, my suspicion is that it is all in the Effects when you create them in the EFX Manager -- since the 105mm Effect is of a single pinpoint explosion, it would not that the physics of the Napalm.
So futhering your quest on this, is pretty much done at this point.
As for the directionality of the Air Drop, again, that is all Physic.
You pick a Target -- or basically call in a set of Coordinate for an Airstrike. A couple of fast flying jets come zoooooooooooooooming in and drop their ordinance at the best possible time to attempt to hit your coordinates.
The way the script works, is the the Jet flies in, drops the bomb, the bomb falls not straight down, but at an angle on a decent path to the ground.
When an explosive is static, and explodes, the physics tell us the explosion will be perfect -- basically explode in a perfect circle -- there is no gravity, there is no directionality, there is no velocity
However, in the case of the Airstrike, Napalm, and Nuke, there is in fact gravity, and directionality, and velocity -- so instead of a static explosion with a perfect radius, you now have an explosion where the destructive path MOVES with the gravity & the directionality & the velocity of the falling bomb
