Factual error: When Columbo initially latches onto the radio dilemma (which ultimately solves the case) the dial is tuned all the way to the left. He later tells someone that the radio is set to 'Classical 52', but an AM radio starts at 54, meaning 540KHz. There is no 52.
Factual error: To make a call, Mr. Bremer enters a seven-digit number on a push-button telephone. The first three keys he punches are 1, 2 and 4. No telephone number in the United States begins with a 1.
Factual error: When Mrs. Williams takes Columbo flying, she does some aerobatics. Neither of them is wearing a seatbelt. No pilot would do that.
