Baggage should never be left out in the pouring rain by the ramp handling staff. It should be put in a baggage cart with a metal top and nylon curtains to keep out rain and snow. This probably happened because the ramp handler does not have the proper equipment and/or has not trained the staff properly. Also, there is certain dangerous goods cargo that is shipped on passenger airplanes that is marked "Do Not Get Wet". This is usually an oxidizer that can turn into a fire if gotten wet. I wonder if UA Express treats their cargo like they do the baggage?
