A constipated outflow valve?


Normal cabin pressurization changes the air in the cabin
very rapidly and lavatory air should not be cycled into the
main cabin. What kind of aircraft and did it have some
special modifications?

I heard on the radio news, it was the smell of the woman's
matches as she tried to burn the smell.

Yea, they're reporting that the pax reported smelling "burning sulfer".
That seems to match with the facts. The woman also reported that she
has an unspecified medical condition that causes such things to be an
issue. Only a woman would do this. If it were a guy he'd walk of there
with a polite warning to other passengers to not go there for a few
minutes.
