Nothing ventured nothing gained as they say, and almost all aviation safety rules are written in blood. I have lost close people too, happens every year, this last weekend a skydiver at my zone broke his back. Innocent kid who may never walk again for a simple hop-and-pop. But skydiving goes on, as does flying. A few weeks before that I posted about an IFR student I used to know who augured into a swamp near Savannah Georgia in low weather. Sure it's heart rending, but every accident gets a case review, and I do not think the spirit of aviation should stop because of its failures. The thing is to manage safety in agreement with the requirements of the risk. There will be mistakes and unknowns, but we should get back up after mourning the lost, making a study, and dusting ourselves off.
