Wing Walker

I have never seen wing walking at the air show before. Peggy Krainz has been wing walking for about 10 years and she has done about 600 displays in that time. The view from the top of the wing must be quite impressive, especially when flying upside down or in vertical flight as in the photograph!

Note that the aircraft at the show was not a standard Stearman. Its specs are shown in brackets below.
