Passengers & crew
No "rain in the plane".

During take-off and landing, passengers and crew are often exposed to what is commonly called "rain in the plane". Especially during descent or take-off, when water seeps along fissures in ceiling panels and people on board are exposed to dripping water.

This is caused by water floating on surfaces on top of the overhead panels. It is condensed water that has not been drained out of the aircraft. This is not news. The news is that you can actually prevent this from happening.
 
Effective insulation.

Mould. The only thing that benefits from wet insulation. Condensed water permeates the insulation making it heavier and significantly reducing its insulation effect. When people on board feel cold draughts at windows and doors, this is one of the explanations.

Also, since wet insulation is the perfect environment for mold, fungus and mildew, passengers as well as crew and maintenance staff may develop allergic reactions. During maintenace, parts of the insulation may have to be dried or replaced.

This entails extra costs for the airlines, while still only providing a temporary solution to the problem - once the aircraft re-enters service the insulation will soon be soaked again. 

A first indication of a wet plane is foggy windows
