Boater chases mysterious periscope off Hollywood beach, Palm Beach Post, June 20, 2010:
Ryan Danoff was fishing with two friends about four miles off Hollywood beach Sunday...
Danoff, a Fort Lauderdale fish farmer who's on the water at least three days a week, aimed his 31-foot center console Fishy Business at the mysterious upright and found himself eye to eye with a periscope.
"It was crazy," he said. "If it was just myself out there I wouldn't believe what I saw."
Danoff moved closer. "It took off," he said. Very fast, about 20 knots. The periscope sank beneath the waves, and whatever was below the surface blew its ballast, sending aloft a mighty hiccup of bubbles. After five minutes the sea lay once again undisturbed.
