For the record, a couple Atlas rockets did crumble under their own weight due to unexpected loss of pressure: https://www.youtube.com/watch?v=imkdz63agHY https://www.youtube.com/watch?v=imkdz63agHY And some Atlas missiles on display are still being pressurized to this day: http://heroicrelics.org/ussrc/atlas/dsc18272.jpg.html http://heroicrelics.org/ussrc/atlas/dsc18272.jpg.html Like really, there is a compressor next to the rocket that keeps constant pressure inside against the slight leaks. Pretty impressive for 40-50 old rocket left outside exposed to the elements to be still this airtight. :)
