400lbs is not a lot of pressure to generate.

Im certain that if the right organization wanted your fan memorabilia, any member of that organization could level that door with the same opener that got them in the first one. pretty sure 1 solid kick is 2x 400lbs +..

id like to see the magnets move a latch, that way... if you kick it in, you take the whole door frame.

i agree that while the idea is epic, execution isnt quite up to par.... light loss is an obvious fail. not modifying the door frame to no longer look like a door frame, also a fail.

correct me if im wrong...but, your house plans are public record in USA. before a warrant is served, they would pull your records, and have a team meeting about where they will enter and the path they would take.

missing a basement is unheard of.... finding a clever void in your houses walls (under stairs) may present a clever way to mask a space that may not appear to be usable.
