It is like saying that there is an upward force on the wing from the air because there is a downward force from the wing on the air. This is self-evident or trivial and does not explain the miracle of flight.Claes Johnsonhttps://www.blogger.com/profile/07411413338950388898noreply@blogger.comtag:blogger.com,1999:blog-1500584444083499721.post-81561795888766883452012-08-07T15:13:24.302+02:002012-08-07T15:13:24.302+02:00Claes,
