Here is the back story of Pops..if roger approves.
Jonah "Pops" Hicks is in his late 50s to early 60s. A drummed out Alliance Officer, been out 10 years before the war running his own business shuttling people. He somehow got his hands on one of first Knorr class transport prototypes which he flew through the end of the war.
how it happened:
Some nine years before the Unification War, ship designer Contessa Herkeimer set about designing the light cargo transport to supply the needs of Border and Rim freight shippers. The result was the “Knorr.”
Her design was fairly radical for the time, and seems to polarize opinions. Johan had worked there for years and had become the Senior Quality Engineer in Research and development. Although he didn't really support any political side he had to join the Alliance to keep security clearances. He was awarded the rank of Captain which would allow he to fly. As his job he would review designs, check and test prototype crafts to see that they met specifications before turning it over to a test pilot who then push it to it limits.
A hot shot young pilot got cute attempting a vertical landing of an early design Knorr and lost control of the craft. It swung toward the observation area. Herkeimer's daughter had been on the tarmac with Johan and the other engineers. As the thrusters were melting and burning a path toward them the group fled to the hanger. Jonah scooped up the young girl rushing her to the safety of building. They were able scramble through the door, the girl safely clear of the danger, but as Jonah turned back to pull the door closed the backwash flashed through burning his face and hands. The burns left his face badly scared with pinkish wrinkled skin. (He now wears a full bread to cover the scares.)
The pilot was from a wealth core family and eventually the blame was place on a malfunction the Jonah had missed. The family saw to it that Jonah lost his job and his commission. Herkeimer however knew the truth and felt indebted to Jonah for saving his daughter. He helped Jonah move out from the core plants and set up a shuttle business. By spreading the word Jonah became nearly a personal shuttle service many friends and family of the Hereimers. When the war started he turned the business into a diplomatic currier service that got him clearance in and out of many planets and situations.
Jonah never really support the Alliance, that young hot shot had become a ranking officer and his recklessness had cost the lives of many of his own men. He had also ordered many of the unnessary bombing in Serenity Valley.
Pops has varied background. He can fly, cook, open locks, fix computer, hack programs and other unexpected skills. He says he was too old to be a Browncoat, but he seems to have been in a lot of places when someone was needed on the QT.
