Hello fellow glider/sailplane pilots...
many years ago I had the opportunity
to see a movie that featured two
1-26's chasing each other...

For reference, the movie was called Dawn Flight, starring
Denis Arndt. The aircraft were 1-26E N1134S and N17925,
with N65932 used as a solo camera chase and an anonymous
(probaby N2476W) 2-33 used as dual camera chase. The
footage was shot on Mission Peak in Fremont CA and
probably also in Vacaville and Calistoga.

I think this might be the IMDB entry for it:
