And at the end of the day in the Pitts, in order to cover the inherent risks you would be paying for insurance that would make the flight an unacceptable risk to your wallet .... This has been well proven to be the killer of all types of light aviation in the past (eg end of Piper / Cessna) until sanity prevailed and the US govt enacted legislation to end the mostly spurious claims. If you are going to do the activity that will increase your heart rate accept that it might bite you on the bum and leave it at that, if not stick to the 737-800 for your aviation jollies.
