India's largest airline, IndiGo, has invested Rs 10 crore in Bengaluru-based Sarla Aviation, a startup developing electric flying taxis. This move follows IndiGo's previous non-binding partnership with Archer Aviation, which has now fallen through due to timeline issues. Sarla Aviation's Shunya eVTOL is designed for urban environments and aims for a 2028 launch in Bengaluru.
