Who is Casey Othic from Time's Eye and what is their importance?

Chief warrant officer by rank, Casey is a short, bulky man. As prime pilot, he flies an observational helicopter. He has a broad jaw and is an Oikumen like his copilot, Abdikadir Omar. Casey has a forward attitude that is heavy with sexual innuendo, but can put all of that aside when his job requires his attention. He was born in Iowa in 2004, and is a jock and a Christian. Despite having his tail rotor hit by an RPG, Casey manages to level Little Bird out before reaching the ground and although the landing is tough, they all survive it.
