Hapo Community Credit Union is this year's sponsor of the Over the River Air Show at Water Follies.
The show will include two F-15s from the 173rd Fighter Wing of the Air National Guard from Klamath Falls, Ore., a P51 Mustang and an F-16 Fighting Falcon, also know as the Viper, from the 388th Fighter Wing at Hill Air Force Base, Utah.
Robert Young Apartments, which sponsored the air show in the past, will be backing the Snowbirds' performance in September, said the Tri-City Water Follies Association.
Unlimited light hydroplane racing also returns this year.
Officials expect about 15 unlimited hydroplanes to be at the July event. For more information, visit www.waterfollies.com.
