An IndiGo Dreamliner flying from London Heathrow to Delhi returned to the airport early on Wednesday, 23 September, after a technical issue was detected shortly after take-off. The Boeing 787-9, operating flight 6E4, was airborne for about an hour before the pilots turned back as per standard procedures, flight tracking data shows. The aircraft transmitted squawk 7700, the general emergency code, Gulf News reports, adding that unconfirmed claims of smoke have circulated. The plane landed safely.

IndiGo issued a statement apologising to passengers and offering hotel stays and alternate flights. The aircraft is undergoing maintenance checks and will resume operations after securing all necessary clearances, the airline said. Specific details about the technical fault and the number of passengers could not be confirmed, several sources including PTI report.
Update, 30 September 2026: IndiGo has now issued a statement confirming the technical issue and apologising to passengers, offering hotel stays and alternate flights, the later Times of India, Siasat, and Gulf News editions report. Gulf News adds that the aircraft transmitted emergency code 7700 and notes unconfirmed smoke reports. The earlier Times of India and Hindu Businessline, citing PTI, had said no statement was available.
The six sources report the same event with near-uniform facts: an IndiGo Dreamliner returned to Heathrow on 23 September after a technical issue, airborne for about an hour. The key difference is timing. Timesnownews and the early Times of India and Hindu Businessline versions, published within an hour of each other on 23 September, state that IndiGo had issued no statement and specific passenger numbers were unknown. By evening on the same day, Siasat, Gulf News, and a later Times of India version carry IndiGo’s statement apologising and offering hotel stays and alternate flights. Gulf News adds the detail that the aircraft transmitted squawk 7700, a general emergency code, and notes unconfirmed claims of smoke.
