Pilot lands plane with rogue snake in one hand
Man grabs unwanted 4.5-foot co-pilot behind head, gets quick
clearance

CHARLESTON, W.Va. - The much-talked-about movie "Snakes on a Plane"
doesn't open until August. But Monty Coles doesn't have to see it.
He's lived it.

Three-thousand feet in the air on Saturday, he discovered a
four-and-a-half-foot black snake peering out at him from the instrument
panel of his Piper Cherokee.

....

Next, he told the control tower he needed emergency landing clearance
and that he had "one hand full of snake and the other hand full of
plane."


{Is there a special squawk code for such???}
