An official from India's Civil Aviation Ministry revealed that a 20-member technical team from Boeing would reach India on Sunday to work on revamping of problematic batteries from Monday. Speaking on the topic, the official added, "If all goes according to the plan, the Dreamliners could be back in operation by middle of next month."
