A packed passenger jet was forced into a FIVE hour delay after all the toilets on board became blocked with ‘something solid’. The Pakistan International Airlines Boeing 777 jet had to make an emergency landing in Manchester when it was revealed the ENTIRE lavatory system got choked.

The flight had been en route from Toronto to Pakistan on Saturday when the mass blockage was discovered somewhere over the North Sea. PIA spokesman Danyal Gilani, based in Karachi, Pakistan, said something had been thrown down one of the toilets and blocked it, which then clogged up the whole system.

According to the Manchester Evening News , he posted a statement from the airline on Twitter shortly after the incident. It confirmed the flight had been forced to land in Manchester saying: “Toronto-Lahore flight PK-798 has been diverted to Manchester as its toilets got choked, due to something solid thrown in by passengers.”

It’s understood the plane was diverted for a total of five hours while the pipes were unclogged.
