crewing up

Verb

crew up (third-person singular simple present crews up, present participle crewing up, simple past and past participle crewed up)

1. (intransitive) To join a crew
   • Although offered to us bona fide, this opportunity to crew up on the basis of our mutual and personal choices was largely illusory in practice. The reason for anyone wishing to crew up and fly with certain other selected individuals was generally self-preservation pure and simple.2003, Murray Peden, A Thousand Shall Fall: The True Story of a Canadian Bomber Pilot in World War Two
