NATURE’S WAY OF INQUIRING AS TO HOW OUR SPACE PROGRAM IS COMING ALONG: Largest fireball since Chelyabinsk falls into the ocean: Nasa reports huge explosion of seven meter space rock over the Atlantic. “It released energy equivalent to 13,000 tons of TNT, which is the same as the energy used in the first atomic weapon that leveled Hiroshima in 1945. This was the largest event of its type since the February 2013 fireball that exploded over Chelyabinsk, Russia, leaving more than 1,600 people injured.” Long-haul pilots report this sort of thing occasionally — I remember an event over the Northern Pacific back in the 1980s that was written up in Science — but as global surveillance gets better, we have more records.
