This document summarizes an article about the development of a personal hobby helicopter in Hungary. It describes how two Hungarian engineers, Kov叩cs Otto and Szirmay Roch, designed and built prototypes of a helicopter using new polymeric materials. Their helicopter, called the "Sting," could take off and land in courtyards. It had a parachute safety system and was approved for recreational use after testing. The helicopter had a maximum speed of 120 km/h and could carry one passenger with a maximum load of 200 kg.

1. Hugh Jackman's hero goes for claws and F/X in X-Men Origins: Wolverine
So, the makers of the industrial-strength franchise extender X-Men Origins: Wolverine have now
revealed the psychological roots of the famous berserker rage that has caused the titles angry
Marvel superhero to bare his adamantium claws in three previous X-Men movies. The question
is, was anyone wondering? Or are you, like me, content enough to admire the cool, crazy talents
of a society of freaks and geeks who find comfort in pooling their misunderstood powers? To
put it another way: Is it possible to make a movie about a superhero these days without
injecting scenes of dreary superambivalence between expensive action sequences? (Batman,
Spider-Man, and the Hulk? Big brooders.) Or is blessed freedom from neurosis granted only to
villains? (The Joker? A fun guy.)
The questions arise as Wolverine launches a new X-Men franchise based on origin myths that
will allow for a pageant of younger stars. In the case of the superhero born James Howlett
(known off duty as Logan, and boasting the Sexiest Man Alive beauty of entertainer Hugh
Jackman), traumatic past experiences include a fatal misunderstanding back in 1845 with a
sinister-looking man the young Wolverine-to-be couldnt have known at the time was his real
father. (The lad also couldnt have known hed grow up to sport a Paulie Walnuts hairdo.)
