The pressure in the lox tank is already supporting the ida..unless the
failure causes a load concentration say pushing the electronics boxes into
the dime..the dome would support ida just fine...

If the Dragon trunk collapsed, the nice round IDA1
under high gees, the pressure would go up in the LOX tank. Even if the
would fit nicely over the LOX bulkhead truncated cone.

The "counterintuitive" comment may mean that we're all up in the night
here and anyone from SpaceX reading this is not getting any useful
information. Of course, something that seems "counterintuitive" to
someonenot familiar with cryogenics may be more intuitive to those who have
experience with weird things like geysering or film boiling...or
who really understands BLEVEs (not me).
