Flatpack stadium to be taken down and reassembled where/when needed.

What a great idea.  They are comparing it to Ikea furniture.  But on the other hand that’s scary.  I’ve never seen a piece of Ikea furniture that was quite as sturdy the second time you put it together.  The Olympic stadium as one of those traveling carnivals that set up in the parking lots of big box stores.  Umm, it’s kind of fun to be scared to go on a structure/ride designed to be disassembled in minutes, but tens of thousands of rabid fans in a ready to be disassembled stadium, might be something to think about.
