The only other bit of information regarding the accident can be found on the
Derbyshire Constabulary website.
The hang glider was reported: "getting into difficulty and falling to the ground from around 50 ft."
Understandably, no-one is giving any details to the press whilst an investigation is underway; so there's not much for anyone to discuss until the AAIB have published the accident report. However, this thread can still be used to express our sympathies for the girl's family.
