The outside of the tank was over 8 meters of of the lobby floor, so no passing by to stick anything to it.

pcprogrammer:
True, but I doubt it to be fully open. To much of a liability on someone getting hurt. And then still the inner tube may have survived and not have been the cause of the whole ordeal.

tom66:
If the inner tube broke first, the failure would have been to flood the lobby and lift with water and fish, but the tank itself would still look relatively intact.   Instead, it looks like the outer wall failed first, and in the collapse, it may have damaged parts of the inner tube.

This is speculation I think which originated from the police, but I am sure the lobby area was heated somewhat; to not do so would be greatly uncomfortable for anyone walking through.  However, it *is* conceivable, due to the current price of energy, that the heating was reduced.  So perhaps instead of 20C, with a 6C delta between the inside and outside, maybe the lobby was kept around 15C, and maybe colder overnight?  I am not sure what the law is in Germany, but there was something about public buildings being restricted for heating in winter due to gas shortages, maybe this applied to hotels too?

More speculation. There was a large bar and café in that lobby, right beneath the aquarium. People were meant to sit there, eat and drink and be comfortable. Rest assured that it was not at 15°C.

Sheesh, of course the elevator cabin was fully enclosed, by transparent walls which were part of the moving cabin. You could, like, squeeze your fingers otherwise.  :palm:

The level of uninformed speculation in this thread is particularly bad. Why not use at least the publicly available information?
