Im guessing. These are registered as bank airplanes. Insurance people maybe? N307DM A339AA WELLS FARGO BANK NORTHWEST NA TRUSTEE - SALT LAKE CITY, UT N307DM United States Civil 1978 BEECH 200
I believe they are the holders of a lien or trust (IE "TRUSTEE" in name) or are the leasing company not the actual users. I've seen the same listing for a number of aircraft which were definitely not bank/insurance planes, as well as commercial aircraft. Here is an example of that listing on a Skywest Aircraft: N896SK AC5D38 WELLS FARGO BANK NORTHWEST NA TRUSTEE - SALT LAKE CITY, UT SKW3605 United States Civil 2006 BOMBARDIER INC CL-600-2D24 CRJ9
Ah good point. Well, the interesting part was the patterns anyway. We had a couple Tecnams flying low at 4000 ft doign block by block mapping too. With the Beech's doing larger surveys from 15000.
