Many years ago....at the Eugene Oregon regionals on my last flight of the day...
I gave the 'starting signal to the judges...fired up the old Sting Ray....ran out to the handle...gave the release signal to my helper....
On the second level lap...
I smelled something burnin' IT WAS MY RAIN JACKET COAT TAIL...IT WAS ON FIRE....With hardley a TWITCH...I slapped out the flame with my left hand and kept on flying....
After the flight was over...I noticed just how close I came to becoming a roman-candle.
That old Merco always had a bad habit of belching on first flip...it would start running backwards for a few pops...and then start running the right direction.

How many times over the years have we noticed after engine start ups...that we would some times have FIRE IN THE HOLE...or somewhere else? Amazing just how difficult it is to actually see alkeee' flames before damage can be done.
With that in mind...I think this attached photo would be the perfect flying suit.
