On Socotra, an island 250 miles off the coast of Yemen, the roads are so bad that 90 minutes of tailbone-bruising driving equates to five miles of travel. The roads would be one reason to paraglide over the island. Another reason would be the scenery. Sugar-white sand dunes spill into turquoise surf. Pink cliffs rise abruptly from the beach. Dragon's blood trees, plants that look like giant umbrellas and can live for more than 300 years, pop up suddenly from rocky scrub.
