Wyvern wyvern is thought to have derived from the figure of the dragon encountered by Trajan's legions in Dacia. It may be the origin of the red dragon of Wales and the golden dragon of the Kingdom of Wessex carried at the Battle of Burford in AD 752. The concept of winged snakes is common in cultures around the Mediterranean, with a notable example being the Egyptian goddess Wadjet. The oldest creatures outright referred to as "winged dragons" are Helios' chariot steeds, which aid Medea. Wyverns are very similar to dragons, and in many languages, cultures and contexts no clear distinction
Westland Wyvern while in service and testing there were 68 accidents, 39 were lost and there were 13 fatalities; including two RAF pilots and one United States Navy pilot.
