costs quite a lot to get to a level where you can wingsuit by yourself from a cliff
costs something like £1800 to get a parachute license, then you need another 200 skydives before you can jump a wingsuit bringing the total to about £8000.
Then £700 for BASE training.
£500 for birdman training
then its another £2-4000 for the wingsuit/parachute/accessories
you then will want to do loads of plane and heli drops costing maybe £2000 to get comfortable
you're looking at around £15,000 to get to the point where you can do this and a hell of a lot of time.
would be awesome to do though.
