"We have ordered a detailed investigation into the matter and both the pilots of IndiGo airlines have been off-rostered. The ground staff will also be questioned during the investigation. Both the flights have been grounded for detailed inspection," the official said.

"The wingtip of a taxiing aircraft of another airline grazed one of our aircraft, which was stationary and awaiting clearance to enter the runway at Kolkata for a scheduled operation to Chennai. The aircraft has since returned to the bay and further investigation is underway, for which we are coordinating with the regulator and airport authorities. We apologise for the inconvenience caused to guests due to external circumstances," an Air India Express spokesperson said.
