Fireball patches [Series X-The Promised Land]

Here we have two flaming, hot-rod fireballs, in red, orange, and yellow. They can be found below and across the Skylab patch on the screen-left sleeve of Lister's new leather jacket from Series X-onwards.

Cast-iron Seven Degrees of Separation to Red Dwarf: their musical namesake, Great Balls of Fire also features in Top Gun, which sees Tom Cruise wearing a jumpsuit boasting an F14 Tomcat patch; the story, characters, and theme tune of which is intermittently parodied throughout, Dimension Jump. 

How many degrees is that? Oh, well. Enough, probably.
