So, Red Bull, can you tell us how much experience you have to comment on the P-51 pilot's actions after losing his canopy?
I know the pilot in question well, and as a fellow display pilot I can tell you that he is one of the most experienced and professional warbird pilots in the UK. I also know that he spends a great deal of time in the winter months tuning his aircraft to an extremely high engineering standard for the summer display season.
As you have absolutely no idea why the canopy came loose and the circumstances that he found himself after it had, you are in no position to pass judgement irrespective of your experience.
Thank you for bringing our attention to the incident on the forum, but please keep your opinions to yourself until the facts are known.
