Question 1: Is it illegal to parachute from a paraglider in the UK?
The jumper and pilot would know and understand what they are doing. Jump would (ideally) take place over an unpopulated body of water. There would be a briefed person on the ground to react in case of an accident. Equipment would involve BASE parachute and an unpowered tandem paraglider.
I am aware that 'normally' skydiving takes place in designated areas, with all manner of controls and regulations. This activity would take place outside of these controls, regulations, British Parachute Association etc.
Question 2: If this is illegal, is there a way that it could be made legal - as a 'stunt' or similar...?
