I was just flying flight 2 of the Trip Around the World, and well I crashed. I was doing okay, except that my computer has trouble understanding the word acknowledge, until..... My Baron decided to do something weird. I lost all radio communications. I discovered that the heading was not right either, and I could not get it to set right. So fine I was about 22 miles from the airport when this happened. I will have Michelle land this plane. That didn't happen. The plane just kept descending even though I set the autopilot to hold at 7500 feet. I crashed at around 4800 feet. I am also noticing that the Baron I am not getting the flight following announcements as I do with other aircraft. Jordan
