Well from personal experience, I learnt to fly in the Grumman Lynx which was a development of the BD1, flew the cheetahs and tigers and got my initial twin rating in the cougar ( a twin engine development of the design) I also had the pleasure of flying the BD4 so it would come as no surprise to anyone that I have followed Jim Bede's career over the years with more than a passing interest and like Rutan, he has his admirers and critics. A case in point would be my experience of some peoples' opinions of the Lancair when I was flying one.... until I took them up.. One guy for instance wouldn't get in it but his wife did and when we came back she had a grin from ear to ear and as she climbed out she commented that it was better than sex LOL.. That sort of changed his mind a little so he nervously got in and I took him up.. He came back with a totally different perspective because he was more informed.. and that's my point, there are a couple of misinformed comments above. Guys like Neubuer, Bede and Rutan do push the envelope and design aircraft using different materials and concepts and this has resulted in a division in opinion.
The tragic accident that spawned this thread no doubt will be the subject of a lot of conjecture until the FAA releases its findings but to me it does have all the hallmarks of trying to keep a low inertia aircraft flying with insufficient/no power back to the airfield as witnesses commented on the distressed nature it exhibited.
