Flying Reptile The Size of A Small Airplane

Posted by Zonk on Saturday September 10, 2005 @09:31PM from the mind-the-droppings dept.

An anonymous reader wrote to mention a New Zealand Herald article about a pterosaur that has been discovered to have an almost 18 meter wingspan. From the article: "A Spitfire has a wingspan of 11m and has to be powered by a Rolls-Royce Merlin engine. Pterosaurs did it on a diet of fish and a superb ability to utilise air currents, thermals and ground effects. There is nothing close to pterosaurs alive today. Pterosaurs went extinct 65 million years ago, they left no descendants and we don't know quite what their closest relative was."

better compare it to a glider. by Anonymous Coward · 2005-09-10 21:57 · Score: 5, Informative

Todays gliders made of composites have a wingspan of 18 meters. Actually they vary from 15 to 24 meters, but 18 meter is a standard class. Optimal speed is usually around 90 km/h and minimum speed is around 70 km/h. Of course a glider is built to carry a payload of about 100 kg.
