Word of advice, be careful with McNair and Onizuka, they got really tricky with them. However, Resnik, Scobee & Smith are undeniable and the odds of these people having the same name, age and distinct facial features is beyond statistically impossible. You could MAYBE find a doppelgänger out there but they will never be the same age and have the same first and last name as you. Now imagine this virtually impossible scenario happening to three (maybe even six) people from the same space mission.
