A man boards a 727 to Denver.
For reasons he cannot explain,
he immediately exits the plane.
Leaving the terminal, the man
hails down a taxi, telling the driver
to take him to Denver, asap.
A moment later,
the taxi takes off into the air,
crashing into the 727 to Denver.
How did this man know the plane was going to crash?
