What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot was enroute from santa rosa (sts) to concord (ccr). The weather at ccr had deteriorated and he attempted two instrument approaches without success. He then requested radar vectors to napa (apa). Travis approach control provided the vector. He saw a runway below him and assumed that is was apa. He reported to approach control that he had the airport in sight and was cancelling IFR. Approach control advised him to squawk VFR and frequency change approved. He subsequently spiraled down from about 3000 feet and landed on runway 3L at Travis Afb (suu) without authorization from the tower. He was then met by security. He stated that he attempted to contact apa but there was no response. When the security informed him that the tower at suu is 24/7 he responded: "I'm at Travis?" The weather at the time was reported 1/4 mi with a vertical visibility of 100 feet.
