I believe Steve has already issued a fairly stern warning on this subject, and I see no use in continuing it. Whether you have confidence in a company or not is not approriate. Vote with your wallet.

Pat, I have very serious doubts that you will have any problems. Even if they extend the runway to 13000 feet ( in case an Air Force pilot has to land there ) you are still a mile from the airport, a
