The deadly crash of Air India Flight 171 last week has centered renewed scrutiny on the airplane's manufacturer, Boeing. This time it's the 787 Dreamliner in investigators' sights. The accident, which killed over 270 people, was the first fatal crash for the Dreamliner since the model began flying in 2011.

Sumeet Sabharwal, who the Indian government has said had 8,200 flying hours of experience and was also an Air India instructor, was the commanding pilot of flight AI171. His co-pilot was Clive Kunder who had 1,100 hours of experience. Sabharwal's funeral took place in Mumbai on Tuesday.
