Kate Middleton rows dragon boats, Prince William shows off waterbirding helicopter maneuver in Canada
Kate participated in some dragon boat racing, acting as both a rowing member and trying her hand at the steering. She did participate in Crew at St. Andrew's, where she and Prince William met, so she fits right in with the Canadian teams.
Meanwhile, Prince William was busy participating in a "waterbirding" demonstration with a Sea King Helicopter. He landed on the water and turned circles, sort of like a giant duck. William is a as a flight lieutenant with the Royal Air Force and as such, he's a fully qualified helicopter pilot. He flies a British Sea King as part of serving for the Search and Rescue Force.
Looks like fun, William and Kate. Can't wait to welcome you to the U.S.!
