William "Randy" Humble, 60, had been flying a Lake Amphibian DA-4-550 performing an aerial show with another aircraft around 5:30 p.m. Saturday.

My sympathies go out to his family.
I'm sure he was donating his time and money to raise funds for the GOP meeting.

Why does it say, experimental on the edge of the wing when the float is down if it's a production plane?

Sympathies to the family and friends.

My brother is a GA pilot and I'm glad he doesn't fly anymore.
