For a Viggen an example figure is 800 km/h, 20 m, 5 degrees up. You'll then fly an 1100 m arc, with a top of about 80 m. - Urban ___________________ \--------------------------/ Urban Fredriksson \--------------------------/ \ My opinions are my own, \-------------------/ I do NOT, and is not / \ but you may share them. \ Nokia Data AB / allowed to, speak for / \ +-----------------------+ Stockholm / my employer! / \-| The best way to get |___Sweden____/-------------------------/ | rid of an enemy is to | | make him a friend. | +-----------------------+

Actually, even that isn't necessary with the best modern seats. The latest Martin-Baker seats can land you safely from an ejection in level flight, upside-down, at 100 feet! Note also the MiG-29 seat that landed Anatoly Kvotchur bruised but intact after ejecting in a near-vertical dive at under 200 feet during the Paris Air Show. -- "Maybe we should tell the truth?" | Henry Spencer at U of Toronto Zoology "Surely we aren't that desperate yet." | henry@zoo.toronto.edu utzoo!henry
