We interrupt our regularly scheduled aviation programming to bring you…diving. Why? Because I have pictures from the Florida cave dive. Not nearly as much fun as flying but still a great sport. Similar to aviation, equipment must be in good working condition, training is required and there’s risk management. Few venues are as risky as cave diving. Not night diving on a shipwreck. Not search and recovery in near zero visibility which is plenty creepy when a freighter passes overhead. The water wasn’t nearly deep enough and we could only hear the engine but not see the screws. Ice diving? Only for those who have lost their minds after repeatedly freezing their brains.
Cave diving demands redundant systems and managing acceptable risk. The most important reason: No vertical egress. If you run out of air or have an emergency (embolism et. al.) you must return the long way and ascend no faster than one foot per second. A dive computer helps but a dive buddy is a safety requirement.
Another thing. Cave diving has plenty of challenge but there’s usually not much to see compared to ocean reefs and shipwrecks. The visibility is the best, so you can basically see nothing perfectly. The deepest I’ve tried was about 100 feet with none of it straight down. Did I tell you how dark it is without a dive light?
The sign behind me reads: “STOP – Prevent Your Death-Go No Further” The fine print below reads “There is nothing in this cave worth dying for”. Which is true. Longest time in an underwater cave does not produce a winner.
Flying and diving have something else in common: You can’t rationally explain why anyone should go up in a light airplane or down in an ocean. Below, my brother is ready to lead the way.
Not recommended if you don’t like confined spaces.
