The falls are every bit as monumental and magnificent as you imagined, their noise greater than a million migrating wildebeests, their mists visible from 40 miles away. Dr. David Livingstone, who in 1855 became the first European to set eyes on them, named them after his queen (who unfortunately would never see them); they were soon widely recognized as one of the natural wonders of the world. A fantasy destination of every adventure traveler, the falls are a mile wide, spanning the entire breadth of the Zambezi River. As they crash 400 feet to the gorge below, they create a delicate, endless shower of rain, rainbows, and - if the moon is bright and full enough - lunar rainbows that drift in and out of view. At dawn and dusk the sky, water, and mist take on hues of pink and orange, especially during the wet season from March to May, when the cascades are at their greatest capacity and the opaque spray is kicked 1,000 feet into the sky. It is easy to imagine Dr. Livingstone's awe as he wrote: "On sights as beautiful as this, Angels, in their flight must have gazed." So was named today's 15-minute heart-stopping "Flight of the Angels" over the falls, which rates as one of the world's most scenic plane trips.
