Flying out of Palwaukee (again!) in the RG I set my flight plan for 5000 feet, went through the details and took off. About 10 minutes into the flight, Chicago departure told me to expedite my climb to 5000. Ok, says I, wanting to be amicable about it. I increased my vertical speed and thought nothing more. A few minutes later I get the same message. I was passing east of O'Hare, so I figured they wanted me out of the way pretty quick. By now, I was at 3000 feet. A few minutes later, I get the same message AGAIN! By now, I am at 3800, and climbing at 1000 fpm and making about 65 kts headway. Fly on thinks I, it's just a game, what can they do. A few minutes later I found out what they can do. I got another message: 'Cessna OMS, cancel IFR flight plan, maintain Visual Flight Rules'
So, I was climbing as fast as I could, and they canceled my Flight plan. Gee, I guess the FS controllers can be just as big of an a$$hole as the real ones huh? What did I do wrong?
