I have been on the U-853 a dozen times since I started wreck diving in 1976 and this film was the closest to dropping in without getting your feet wet that Ive ever seen .......interesting how there were no control wheels left 10 years ago to bring up, but it wasn't because we didn't look. Great film very nostalgic for a compressed air diver who doesn't get wet deep anymore. Thanks for the memory's. up.
