That is correct, I was not a required flight crew member and the company did not have to have a second person in the plane, nor did they the other 4 out of 6 night they flew. I to do not want to see anyone be forced out of a paying position by a volunteer pilot, but if they are not going to have someone sitting in the right seat anyway, let someone atleast have the opportunity to gain some experience from a more seasoned pilot, if they don't mind.
