Boeing shares will likely remain in focus after slumping to end last week following news that one of the company's aircraft was involved in an Air India plane crash. Monitor these crucial support and resistance chart levels.

Air India flight AI171, a Boeing 787-8 carrying 242 people, crashed after taking off from Ahmedabad on its way to London.

A veteran commercial airline pilot said he may have found a “total game-changer” in what led to the doomed Air India Boeing 787 to crash after analyzing new video.

The passenger jet - the same type as the aircraft involved in last week's tragedy - was bound for New Delhi but landed back in Hong Kong about an hour after take-off.

The Air India flight fell from the sky on Thursday and killed at least 270 people in Gujarat state, officials said Saturday.

Boeing was generating optimism. Then on Thursday a 787 crashed, raising the specter of fresh problems for Boeing and altering the message it planned to send.

AHMEDABAD, India >> The investigation into the Air India plane crash that killed more than 240 people is focusing on the engine, flaps and landing gear, a source said on Friday, as the aviation regulator ordered safety checks on the airline’s entire Boeing-787 fleet.
