You are on an Airbus A320 at 32,000 ft. somewhere over the Atlantic Ocean, westbound. You are listening to your headphones peacefully, when you hear/sense a stir in the passengers. You peek over your seat, and see that an albino midget is waving a handgun in the air. You take off your headphones to hear what the midget is saying with a thick Russian accent: "I've got a bomb sitting somewhere in the cargo bay of this airpline, set to detonate at the push of this button. I have two other Russian albino midget friends that have already executed the Pilot and Co-pilot, and we are now setting course for Washington D.C. Any brave attempts, and I will detonate the bomb." What do you do?
