X-15 contrail
after launch
This photo from a chase plane, first
published in 1962, shows the X-15 pulling up into a climb after
launch. Final climated usually was a bit more than 40 degrees for
altitude flights.
Sunlight refracting through the chase plane's canopy.transforms a
simple image to a work of natural art.
This photo, NASA number EC65-884 has
been widely published and reproduced, usually in the wrong orientation
-- rotated 90 degress counterclockwise. This error is perpetuated to
this day on the NASA Dryden web site and has spread from there to many
other published sources. One that got it right was the September,
1962 issue of National Geographic.
