This info can also work the other way.
Some years ago I was negotiating with an agent to purchase a privately owned a/c. The negotiations were taking some very strange turns. I contacted the CAA, got the owners name and address. Gave him a call and discovered the agent was being very “economical with the truth”.
Result, the seller sold the plane and I saved several thousand pounds.
At the time I was surprised you could phone up and just get the information. I would not think posting it on the net would make a lot of difference?
