Evergreen had to do something wih that whale...
The ‘whale’ you’re referring to - which I’m sure is the 747-400 supertanker - is pending sale after the investors shut it down last year.
The airframe atop the waterpark - it is NOT the original 747-100 supertanker airframe which first dropped retardant in 2009 - is the launch point of 4 of the waterslides.
