MINNEAPOLIS (AP) -- A diver is slowly recovering at a Minneapolis hospital after an accident in the Michigan waters of Lake Superior led to a serious case of decompression sickness.

Terry Begnoche was shooting video of a shipwreck off Grand Marais, Michigan, on September 18th and planned to make a slow ascent from 220 feet down.

But a trip back up that should have taken at least 45 minutes took just two minutes, according to reports.

Loaded with video gear, he neglected to put on a weight that would have controlled his ascent.

The Michigan man says there was no way to stop his momentum.

His decompression sickness was so severe that Begnoche required a low-altitude flight to Hennepin County Medical Center in Minneapolis for treatment in its hyperbaric chamber.
