I was thinking it over and I was wondering why the institute chose to allow Liberty Prime to be destroyed. Why not destroy the air ship and save him?
He's an invincible force that can not be destroyed by anything beyond nuclear means or mass explosions.
Why not have him walk away from the blast radius? If they cant do that then why not just teleport Liberty prime out of the blast radius?
Even with the Insitutes technology, they never created a weapon as powerful as Liberty prime, why destroy it? It just doesn't add up in my mind.
