Shot the Blue Angels performing on Sunday from the top of my condo building. This year, I benefitted from both the autofocus speed of the Fujifilm X-T3 and the reach of the XF 100-400mm ƒ/4.5-5.6 lens. The result was being able to actually see into the cockpits during some of the low passes around downtown. This is also without the 2x teleconverter installed, whose 2 stops of reduced light gathering would have slowed down the shutter speed to being nearly unusable.
Every year for the Seafair air show, the Boeing Museum of Flight holds their Jet Blast Bash, inviting fans of aircraft of all types to watch the U.S. Navy's Blue Angels preflight demonstration and takeoff. Although you don't get a view of the actual air show demonstration that takes place in the box over Lake Washington, it's a great alternative to the endless crowds at Genessee Park if you care more about the airplanes than the hydroplanes.
