In his 2-minute, 10-second test flight, Chretien beat aviation giant Sikorsky into the record books — but it was not without significant risk. As the man himself puts it: 'in case of crash I stand good chances to end up in kebab form.'"
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
