The search for missing Malaysian jetliner MH370 is now at Day 11.
Developments on Tuesday include the search area expanding to 3 million square miles (the continental United States is approximately 3.5 million square miles) and confirmation that the initial turn was entered using the plane's computer.
NBC News' Richard Lui (@RichardLui) sat down with NBC News correspondent Tom Costello and former NTSB crash expert Greg Feith to moderate a live Q&A and answer viewer questions, in addition to discussing how long this search can actually go on for. On-demand video will be available above later Tuesday.
