Boeing stock fell early Monday as investors anxiously wait for updates about what happened to the Air India 787 jet that crashed on June 12 less than a minute after taking off from the Ahmedabad airport.

For Boeing, the Paris Air Show has been a chance to listen to the industry, one Boeing executive says. "What do they think of us? It doesn’t matter what we think of us.”

The crash of a Boeing 787 passenger jet in India minutes after takeoff on Thursday is the latest incident that adds to woes at the troubled U.S. planemaker.
