I have an unhealthy obsession with 17 x 9 px flags. Main Flag Series If you want the backstory for any of the flags, I can explain all of them. You may also use these flags in your signature to show what planets you've visited, your favourite planet, etc. Mission Flags In these, the roman numerals represent the number of the moon (e.g. Laythe is Jool I). You could also use this to signify the number of probes you've sent there. Flags designed to be attached to probes. Debris flags, for craft that are uncontrolled, such as spent stages. Alternate Flags 'MERICAN flags, for all you patriots out there (no damn commies allowed!).
