Passenger stuck on a sweltering United Airlines flight for 7 hours with no food said it was 'like being tortured'

• United Airlines passengers en route to Rome last month were stuck on the plane for more than 7 hours. 
• Scott Rosnov, a passenger in business class, told Insider that it felt like being taken "hostage." 
• Flight attendants did not serve food, provided very little water and did not communicate properly, he said. 

A United Airlines passenger trapped on a plane for more than seven hours on the runway said it felt "like being tortured" after being left without food or air conditioning.
