Hugh Morris for The Telegraph:

A Norwegian flight with a broken toilet was forced to return to Oslo only 20 minutes into the journey – despite the plane being full of plumbers.

The service from the Norwegian capital bound for the German city of Munich – a two hour and 20 minute flight – was carrying 85 tradesmen from the country’s plumbing industry including 65 from one company, Rørkjøp.

But the army of plumbers was unable to fix the faulty loo.
