if anyone is interested there is a pretty good book written by a pilot who used to fly drugs in and out of this island. http://www.amazon.com/Buccaneer-Provocative-Adventurer-Smuggler-Extraordinaire/dp/1939521084/ref=sr_1_3?ie=UTF8&qid=1439150001&sr=8-3&keywords=buccaneer
Here is another book about a crazy battle on Normans Cay between a professor and the Columbian drug cartels. Both books are quite interesting.

That runway was built by the cartels for drug deliveries.
