Narrative:

Hot air balloon flight into class D airspace unintentionally. Did not have aircraft radio onboard. However, other balloon in the air at the same time tried to contact tower and advise we were entering their airspace but was not able to raise tower on radio. We landed as soon as possible. Callback conversation with reporter revealed the following information: the reporter states that 'the other pilot flies in this area all of the time' and that he had the right frequency selected when trying to contact the tower. The reporter does not know why the tower did not respond. The reporter has not heard from the FAA on this incident. The reporter and the other pilot pre-briefed that the other pilot would contact the ptk ATCT in the event that they flew into its airspace and that the other pilot would relay any instructions to the reporter. When the tower could not be reached, both balloons landed as soon as possible.
