In 2009, Collins attempted to break the world record for paper airplane time aloft with his "follow foil."
Using a full sheet of phone book paper, Collins designed a new category of paper airplane you fly using a piece of cardboard. Essentially one big wing, the follow foil is a single length of paper with a simple fold on either end. The tumbling wing is light enough to stay aloft with the updraft created by the angled cardboard, and Collins was able to fly this design for more than 30 minutes.
He showed a video of his 30-minute flight to the judges at the Guinness World Records. He says they were impressed with his creativity, commended his design, and said it was amazing, but then promptly changed their definition of paper plane flights to exclude this sort of flight from the paper plane record attempts.
