Unlike norms, these planes will not be operated by Air India pilots but will be maintained by Air India Engineering Services Limited (AIESL), a subsidiary of the Indian national carrier, and flown by Indian Air Force pilots.

Here are some facts about the new airplanes, as gathered from multiple sources
