When I got to the airport yesterday around 3PM, my door was closed but unlocked. When I close the door, I always try to twist the knob and push on it just to make sure it's latched. I was surprised, but didn't put a lot of thought into it. I unlatched the big door and opened it. I turned around and saw the passenger door on my plane was open and quickly noticed my headset wasn't on the hook behind the seat where I keep it. At first my mind didn't want to accept that something had been stolen. I thought maybe I had left it in my friend's plane when flying the day before, but I remembered I had taken my cheaper ASA headset instead. Looking in the plane, my Bose and my DC Pro X were missing, along with my Icom handheld. I turned around and saw my desk drawer and large cabinet were open. Only then did it hit me... someone got in here and robbed me! None of my tools were missing, and there were a lot of expensive things like fans and heaters, so I assume they just grabbed things they found valuable and small and got out. I went to the airport manager to let him know and tell him I was calling the police. He came over to my hangar and the police showed up. I was surprised the officer actually took fingerprints, which are easy to see on my plane. For once I'm glad it's a fingerprint magnet! All-in-all, I'm mad, but I take things for what they are - kind of an "it is what it is" policy. It could have been a lot worse. I still have my plane and nobody was hurt, so the $2K out of my pocket will sting, but I'll survive. I doubt they'll catch anyone, but you never know. I think the worst part for me is trying to figure out how they got in. The door knob wasn't damaged. Two of my close friends have keys, but I would trust them with my life, much less my plane which is why they have a key. That leaves two other options. I wasn't as OCD as checking my door as I usually am, or someone working for the airport with the master key got in. I hate to suspect anyone, so I'm going to let the police do their job. Will I change anything, probably not. I'm not going to take the time to remove my headsets every time I go home. I'm thinking about hiding a game camera, but if they see it they will just take the whole thing. Feeling tired and frustrated today, maybe I'll be more ****ed after some rest.
