I'll give you a completely different angle guaranteed to bring this
discussion from the sublime to the ridicolous.
A woman here was fairly seriously injured aboard ship, when the toilet bowl
was partially empty of water and suer gases came back into the cubicle.
Underwear on nylons provided the spark, and she was literally blown off the
seat. The phones could be getting the blame in the wrong.
