Servicing and repacking the emerg slides has a high cost, someone said it was about $25k per slide, plus the plane is out of service until the slides are replaced. They might have some spare slides they can quickly install, but if it is like the other spare parts then not likely. So parking that plane for several days is costly.

But having a engine blast apart with flames is ugly on the news, everyone has a camera nowadays, so social media would take it to the max exposure. And I think I read good replacement engines are several hundred thousand dollars but my memory on that isn't sure.
