Synchronized cavern diving
An evening pause: They call this a flash mob, but that’s not accurate. These divers did not mysteriously appear here to move in unison in order to surprise someone. They all planned it together.
Nonetheless where they are and what they do is beautiful. I especially like when they coordinate the pointing of their dive lights.
Hat tip Mike Nelson.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
This looks so easy! I know it is the most dangerous aspect of caving though. Their slow movements must keep the sediments in place. The wires indicate it is a popular cave. They are not deep so was wondering what it is like above the water surface. Any idea where it is?
