We had a maintenance problem arise when we were taxiing out to the runway with passengers on board. When we got back to the ramp, another aircraft and crew was called to take them instead, so the other pilot and I had to take the passengers' bags from our baggage compartment to the other. Needless to say, we got SOAKED! This is not usually what people think about when they imagine the life of a pilot. It's just part of what we call, "Living the Dream!"
