Go First flight under fire for leaving over 50 passengers behind on tarmac

India's aviation regulator has pulled up an airline for leaving behind passengers on the tarmac in the southern Indian state of Karnataka. A flight by Go First, previously known as Go Air, took off from the airport in Bengaluru city, leaving more than 50 passengers forgotten in a bus. Reports said the travellers had checked in their baggage and had boarding passes in hand. The airline said it was investigating the incident. Go First apologised to passengers who complained on Twitter but has yet to explain what caused the confusion. The Bengaluru-Delhi flight took off at 06:20 on Monday even as several passengers were still on one of its buses on the tarmac. "The ground staff was checking whether the flight took off," Sumit Kumar, one of the passengers, told news channel NDTV. "Initially, they said the flight will return." After the flight left, angry passengers tweeted about their experience, criticising Go First for its "negligence".<br/>
