Egli recently took a trip to Toronto to enjoy the sights and catch a baseball game at the (former) Skydome. Stick ball confuses him and he ended up catching a foul ball in the side of the head when he was trying to buy some glizzies. Overall, he had a great time and loved the Skydome experience, he even walked over to the CN tower after the game to see the city from up high. That's when it dawned on him.

Egli's pitch for the new Edmonton arena is to reclaim the Skydome name and to make it true to that name. Four massive towers will stretch fifteen hundred feet up into the sky with an elevator in each one, at the tippy top of those four towers will be a stadium unlike anything else that has ever existed in this world. An open air hockey rink literally in the sky. 

HFFO says that it's impossible, but Egli didn't notice an engineering degree in his office so he still has hope.
