The Royal Aeronautical Society's "Man Powered Aircraft Group" was formed in 1959 by the members of the Man Powered Group of the College of Aeronautics at Cranfield when they were invited to join the Society. Its title was changed from "Man" to "Human" in 1988 because of the many successful flights made by female pilots.

Under the auspices of the Society, in 1959 the industrialist Henry Kremer offered the first Kremer prizes, of £5,000 for the first human-powered aircraft to fly a figure-of-eight course round two markers half-a-mile apart. It was conditional that the designer, entrant pilot, place of construction and flight must all be British. In 1973 Kremer increased the prize to £50,000 and opened it to all nationalities, to stimulate interest.

The first Kremer prize of £50,000 was won on 23 August 1977 by Dr. Paul MacCready when his Gossamer Condor, piloted by Bryan Allen, was the first human-powered aircraft to fly a figure eight around two markers one half mile apart, starting and ending the course at least 10 feet (3.0 m) above the ground.

Our endless enthusiasm for sipping things through narrow tubes has birthed much innovation in the straw market. It has also created a new anxiety: lip wrinkles.
Traditional straws force sippers to purse their lips around the opening in an expression that many believe, over time, creates wrinkles around your lips, called perioral lines.
Enter the anti-wrinkle straw, shaped like the number 7, with a small hole at the top horizontal portion that allows users to drink without pursing their lips.
