Defuse the Bomb

You are an undercover agent testing out the new jumbo jet by Block-Airlines, However this isn't a regular flight! Someone managed to sneak aboard a bomb big enough to engulf the entire plane in flames! It is now your job to interrogate the villagers to find the right person with the device capable of defusing the bomb. Some villagers might giude you with clues. Some might waste your time. You have roughly 10 and a half real-life minutes before the bomb explodes and destroys the plane. Can you defuse the bomb?
