The Blue Angels aren't putting on the show, they are one of the acts, the feature act, but get no money from it. It's these other unknown people using a dead astronaut's name putting on the show.
I see Deke Slayton Airfest
La Crosse, Deke Slayton Airfest Madison, Deke Slayton Airfest Tomah. Looks like they all are about the same show.
Whoever is running this thing is working hard to maximize the income. They're targeting high rollers, low rollers, companies, organizations, and
"club" packages galore. It's so slick I suspect this has been going on for some time. Maybe since before Slayton died in 1993.
But we still don't know who has their hands in the till, the only thing we know is it ain't fargon.
