The shot required the camera to be over the head of the actress - and
is a reflection from a first surface mirror on her lap! Both actor and
actress had their hair restyled to make the reversal non-apparent to
all but us glider pilots. Tom Knauff & Doris Grove had an excellent
presentation on the filming at one convention, followed by a neat
article in Soaring. Now that those are online- you can probably search
for it.
