Every video of human-powered flight has the plane or helicopter so close to the ground that it benefits from ground-effect. Is there any exception to this rule, i.e. a still-air-level-ground human powered altitude record that is high enough to leave ground effect?
The FAI's photo of Daedalus shows its height above the sea to be considerably more than its wingspan, putting it out of ground effect.
(Wikipedia says that most of the flight was 15 to 30 feet high, well within ground effect because the wingspan was 112 feet.)
I couldn't find any official FAI record for height achieved by a human-powered aircraft, though.
