I'm not gunning you or anyone in this regard. Been there, done that and have a garage full of t-shirts. I'm merely drawing attention to the fact that it's technically illegal, albeit leaving no real choice other than to cancel the flight and risk losing the job. Most of the time you make a plan, figure out an alternative way to do things and get the job done. Occasionally things get ugly and people die. Met, proper facilities and decent comms are things airline types take for granted and contract pilots learn to live without.
It's a hard road and just makes one appreciate that airline job a bit more (when you eventually get one....hopefully.).
