Oddities: any idea why that air launched rocket (concept animation above)
briefly deployed a bag aft, after release and why its 4 motor exhausts were
mounted on the top (early Goddard style)?

Note the sentence: "And although the video does not make it clear, the
first and second stage of the rocket are powered by the same four rocket
engines that are mounted below the payload fairings"

So, they seem to route the exhaust gas of the *second* stage through
this lateral nozzles. A rather strange concept, but why not :-)
