I have Ed Gardia listed as HG fatality #12 in September 28, 1972. See the clipping from the Reno Gazette the next day below.
A lot of towing was going in before that.
Two guys died on tow in July and August in the US. Two on boat tow in May - D.C. and France. All rogallos.
One on car tow in Florida in April. These guys had all probably been free-flying after release.
So I couldn't say Gardia was the first.
The first six might have been in Australia. Flat ski kites, maybe, except rogallos were suddenly catching on like wildfire.
I'm thinking rogallos because they had more area than ski kites and were easier to break on tow. I don't know. Still trying to verify these.
So Joe, I wonder who was the guy who got killed at Sylmar?
I think R.V. Wills got confused and wrote in
Ground Skimmer that Gardia had died at Sylmar .
Maybe that film was taken at Slide.
