Aeronut 2008 !

Do you have any figures how much more head wind average the east to west bound crossing consists of ?

Indeed …very little about east to west attempts. It is much harder.

I think Alcock and Brown were very important. Lindy flew non stop from New York to Paris…which was the Zeppelin territory…untill 1937. So Lindy with very long solo flight in a different era was still very important too.

Solar Impulse II crossed the Atlantic Ocean about 100 years after the first ones, but when do we see the battery powered plane crossing the big water ?

Brasilian AF chief is correct. Gripen is almost as stealth as B-2.

YAK-28-Brewer,

Here..they claim SU-57 is superior to the F-22 ( product of the 80-ies ).

I wonder if the wind energy could be stored as kinetic energy ?

Can anyone explain how the polish ANEW succeeds to supercede the “unbreakable” Betz’s limit by 18% ?

They also beat the HAWT propellers by 33% in efficiency on low and medium winds.
