Fixed the second image. For the first photo, the large launch signature is a consequence of a single pyrotechnic charge that ignites both the boost and the sustainer (gas generator) at launch. The sooty exhaust coming out of the Coyote is as a result of unreacted polystyrene beads from the gas generator. Believe it or not, the understanding of two-stage combustion in ducted rocket ramjets is still a work in progress
I'd hope Meteor doesn't trail an F-4 Phantom-like smoke trail like Coyote.
(I'd have never guessed plastic beads though I know ABS is popular with the hybrid rocketry crowd. I'd have expected something more exotic.)
