The end of the races this year was indeed very sad. However, I don't think it tarnishes its' legacy at all. RARA put on one hell of a show every year! Completely unique, it's hard to imagine replicating anything like it going forward, wherever it ends up if it survives.
I was fortunate to attend a half dozen of the events and have wonderful memories of being there. Especially watching my favorite pilot on multiple occasions, Bob Hoover. I did witness a few fatalities and it always leaves an aching pit in your stomach when seeing pilots go down. These guys loved what they did and were well aware of the risks involved when climbing into those T-6 beasts. Consummate professionals, the best in the business. May their souls rest in peace!
