Looks to me that Randall got the chart wrong. Rockets go much faster than fireworks. Very large fireworks can go faster than the speed of sound on the order of a couple hundred miles per hour, https://www.fireworkscrazy.co.uk/blog/how-fast-are-fireworks/

But in order for rockets to go into orbit they have to reach speed in the thousands of miles per hour, http://spaceflight.nasa.gov/shuttle/reference/basics/launch.html

So the rocket ship should be to the left of the fireworks.

Unless the initial acceleration of the firework is faster than the rocket. Does anyone know that? [[User:Rtanenbaum|Rtanenbaum]] ([[User talk:Rtanenbaum|talk]]) 15:23, 28 December 2016 (UTC)
