SpiceJet flight SG-152 had to return and make an emergency landing at Chhatrapati Shivaji International Airport, Mumbai, India, on March 19.
The aircraft, heading from Mumbai to Delhi, was mid-air when it started causing turbulence due to green system failure, prompting the crew to return.
The plane landed uneventfully.
