Whistle While You Work? Not in Space

Former astronaut Dan Barry has seven hours of spacewalking time to his credit. He tried whistling during his spacewalk on STS-96 in May 1999.

“It wasn’t something I hadn’t planned — I thought of it on the fly. It turned out that it didn’t work.,” he said.

Barry called down to Mission Control and said, “Houston, EV2. The science types might like to know that it is not possible to whistle during an EVA.”
