Here are two of the employees of staff from Down to Earth Travel and some of their customers. The rabbit and main pilot is Nigel Hamptoncrater. He's a fine fellow and quite a reenactor. His favorite period is the WWII and to flavor and likes to provide a "historical perspective" for visiting alien tourist. He has a tendency of wearing the shaggy leather jacket, scarf and goggles over his regulation flight suit. He is an accomplished pilot but has received a couple citiatons for barrel-rolling the Pox Terra over the space port after dropping off his passengers.
The sore looking fox is Tristan Twittlehill, formerly of the Royal Marines who was discharged without prejudice, and is now the head of security for Down to Earth. He is also secretly an Alien Conspiracy fanatic who has joined the company to keep track of aliens here on Earth.
The other two are just examples of some the aliens who have popped up so far in the snippets. The slug guys have a charming habit of licking their eyeballs.
