Thanks for sharing. Setting aside that it remains quite depressing to read yet another one of these, it is quite refreshing to see an article that doesn't spend all the copy dissing the pilot and drone safety in general, and that actually there is less sensationalism here than in most articles reporting such an event. I'd even go so far as to say it was quite light on the pilot-error aspect of this, considering the levels of people and danger involved, and the 'near-miss of small child' component.
What is confusing about this one is that the pilot knew enough to attach prop guards and relocate 3 times before launch, in search of stable GPS, but not enough to know that stable GPS is an impossibility in the middle of downtown city block and that he should have been in Atti mode from the get-go. Not entirely sure why the prop guards didn't save him though, and I can't see what makes it go from merely 'drifting' to dropping out of the sky...
But I can't believe he had a 107, so presumably the FAA will go after him and the people that hired him...
