Happy Flyer Goes To Jamaica

Happy Flyer is on a trip to Jamaica and he is only 50 miles away from destination. Now he is faced with a flock of birds in his flight path and he must fly without hitting them. If he hit the bird his plane will crash. Each time he pass through the birds, he is getting one mile closer to Jamaica. Once he pass all 50 birds he can have his dream vacation in Jamaica.

So please help him pass through the birds to reach Jamaica safely!
