It was a rare pleasure to get to see so many of today's best military aircraft all congregated in one place. Gives a guy like me a warm and fuzzy feeling. But I couldn't help but wonder if I was seeing the end of an era in fighter aircraft. With advances in remote piloting, we can now send aircraft into harm's way while keeping the pilots home safe in a bunker. But one thing's for sure, we'll still need ground crews to keep tomorrow's aircraft flying.
