The first video, it seems to me that he needs to get his wing tested too, look at the condition of the wing. The fabric appears to be in a bad condition to me.
hey flydiver 71 ai'nt old!, you are still learning, what and where, and how! (though your'e probably 'peaking'). i knew i had ' peaked' when my wife asked me if i'd rather have sex or fly my trike and i had to look up the weather condition before answering!
well my wing takes only 50 to 70 m for lift off tandem/nil wind condition but its very hard to manure its stretch me left side from very first day .... i think manufacturing defect ... when you are new some peoples keep you chit on ....
So sad, witness accounts don't seem to match the condition of the trike though. Here is a link with more info. http://www.arkansasonline.com/news/2016/jun/20/plane-crashes-conway-airport-police-say/
Grass in good condition is the best I think, but those clumps of buffalo grass in Montana shook my GPS right off it's mount. I don't think I've ever seen one as pretty as Jozinko's !
