Hey!
Obviously, it's not possible for a single person to fly for 64,000 years. That'd be insane, impossible, and frankly a complete waste of 640 centuries.
However, it's possible that the total flights <em>around the world</em> could be combined to make a single time, and cutting off every time there does happen to be a casualty.
A method that wouldn't be very accurate but considerable is making a ratio of time in which there's been no casualties and scaling it up to a larger scale like the one we've been provided.
Hopefully this helps!
