Remember the axiom:  For the loss of the nail, the horseshoe was lost.
For the loss of the shoe the horse was lost.  For the loss of the horse
the rider was lost.  For the loss of the rider the battle was lost.  For
the loss of the battle, the war was lost.  For the loss of the war, the
kingdom was lost.  Yes, I do mean to tell you that the whole kingdom was
lost because someone said "It is just a stupid little nail....."

Hamid,

 

Wrong application of an old analogy - This is the one used to reinforce the concept: break the chain of events before it leads to disaster - When the horseshoe was lost, plan B should have been used - grab the  nearest motorcycle!  The nail was missed in the pre-ride checklist.

 

Rutan has not remained motionless because he waited for everything to be TSO'd (as if that makes things perfect) and neither will I.  That's why we fly aircraft called experimental - amateur built.  It is not that you choose to use trash, it's that you understand you are not placing "faith" in a failure free manufacturer - like Cessna for instance. However, I must admit, success does require some thought and a willingness to accept the results of a failed experiment.
