The plane for the second leg of my trip seems to have issues. During takeoff, a significant amount of condensation came out of the side panels above the seats. It dribbled water all over me and the passenger in front of me. Secondly, there was a significant squeal coming out of the intercom system making it difficult to hear the flight attendant. Lastly, there was an awful speaking sound from the brakes upon landing. This seemed to be an old aircraft and it shows.
