I was waiting for my mate to get through immigration at SEA after a flight from the UK.  He was telling me that there was a horrible line to get through, so I figured I had a little time.  I also knew that Everts Air Cargo’s MD-83 freighter was due to launch out of Boeing Field.  Originally, I had figured I would miss it but, since he was stuck in line, I might as well wait around and get the take off.  A slightly gloomy day but a Mad Dog freighter is still worth it!
