The Canadian team known as AeroVelo is suspiciously quiet after yesterday's flight with their human powered helicopter that ended with the following tweet:

Hit 3.3 metres & 65 sec on our flight. Submitted the flight to the American Helicopter Society; waiting for validation before commenting. — AeroVelo (@AeroVelo) June 14, 2013

The Canadians are one of two teams that have been working hard the past year to claim the $250,000 Sikorsky prize for the first human-powered helicopter than can fly to a height of three meters and stay aloft for at least 60 seconds. They also have to stay within a 10-square-meter area.

AeroVelo and the Gamera team from the University of Maryland have been taking turns trying to successfully complete a record flight, each getting close, but usually ending when the delicate helicopters breaking in the process.

There is no comment from the AeroVelo team after their possibly record-setting flight today. The American Helicopter Society must first review the data from the flight and determine if all of the criteria were met. Team spokeswoman Meg Campbell says it will probably take "at least a week or two" to find out if they have won.
