This is the second bird hit case in two days. On Thursday, a Chandigarh-bound Go First plane returned to Ahmedabad as it was hit by a bird shortly after taking off. The Times of India quoted aviation regulator Directorate General of Civil Aviation (DGCA) as saying that the incident is being investigated.

In a statement, a Vistara spokesperson said: "Vistara flight UK 622 operating from Varanasi to Mumbai on August 5, 2022 turned back to Varanasi due to a bird strike during departure.?

"Due to a maintenance inspection of the aircraft being required, another aircraft has been sent from Delhi to Varanasi to fly the passengers to Mumbai. It has been our constant endeavour to minimise inconvenience to our customers in such unavoidable situations whilst keeping safety as our topmost priority."?

This is the latest mishap to hit the Indian aviation sector this week. Some of the other incidents and regulatory actions taken with regard to them are listed below:
