So I'm working on a B-57 Canberra, armed for low level strike, this load out was normally made up of:

A bunch of 500 and 250 pound bombs in the internal bay. No problem there.

Rocket pods, again not an issue.

And a great deal of napalm, which is something of an issue. Is there a way to approximate the "massive wall of flaming death" a napalm strike would produce?

I know that I can't get the blasts to stay there, but a nice long line of explosions would work fine.
