Are there any examples of sustained human-powered flight above 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.
