Around 30 passengers on a flight in India have been treated for headaches and bleeding to the ears and nose after pilots 'forgot" to flick a switch regulating cabin pressure.
The Jet Airways flight 9W 697 from Mumbai to Jaipur had to make an emergency U-turn shortly after take-off after the pressure dropped.
Videos posted by passengers online showed oxygen masks being deployed.
