I’ve got my A license and FS1 formation qualification in skydiving and I could’nt have done it without the tunnel! i think there amazing and very very fun the most ive done in one day is 1 hour 30 minutes of flying and i was shatterd! but its given me the oppurtunity to learn to freefly and get better at formation in the uk – because this summers sucks! :( whats with all the cloud. Bedford UK for formation, Airkix MK for freeflying – cost effective very friendly instructors would recomend it every time!
