National Paper Airplane Day is an unofficial observance, celebrated on May 26  each year in the United States to commemorate the simple aeronautical toy.
Paper airplane day celebrations typically include social gatherings at which participants create and fly paper airplanes. These events often feature contests in two basic flight categories: "distance" and "time in air". As of 2012[update], Takuo Toda holds the world record for the longest time in air (27.9 seconds). The distance record (226 feet, 10 inches) was set by Joe Ayoob, with a plane constructed by John Collins, in February 2012
The world record for 'flight time' was set by Ryan Bayne in the winter of 2004. While at work one day, he designed and tested a paper airplane that, upon throwing, hovered above his head for a full 35 seconds. After the 35 seconds ended, the plane flew away, over all of the nearby buildings, and has not been seen since. Some say that it is still in the air.
