Narrative:

On return leg of flight, may have inadvertently flown into class B airspace without a clearance. By this point of the flight, I had preflted 3 airplanes before finding one that was airworthy. Was running late. Had not flown at night cross country in probably 6 months. Had turned back after not being able to locate my destination airport, and was tired. Callback conversation with reporter revealed the following information: reporter stated that the main reason for his inadvertent class B entry was the fact that he had misprogrammed the identify in his GPS for the destination airport, causing him to not locate it and then to become confused while returning to his base airport which was underlying the class B airspace.
