A pilot here as well. This article and incident has so much fail in it. There's NO information about the incident aside from the person being injured.
Wifi flying? Only the AR.Drone has it.
All the photos show a DJI flaming wheel 550 hex. It likely runs a NAZA or ACE system. Likely a NAZAv2 as the camera looks like a GoPro and every article mentions iPhone(!). NAZAs only use WiFi for camera and ground station supervisory, not actual flying. It's is a man in the loop system. The pilot still has control via a 2.4Ghz narrowband radio (like a spektrum, FrSky, etc...). NAZA allows you to hit a button (goto waypoint) on the iphone, and it autonomously flies BUT allows user override with the r/c sticks. And the wifi portion only allows 2-3 functions: Land, goto Home, or goto waypoint aside from live video.
When it comes to hacking, there's so much fail here. The guy's obviously is a aerial photographer, NOT a drone user. You can't hack the 2.4 narrowband--it's binded, the iPhone wifi? sure you can hack that, but it's for live video and a couple of 'safe' commands. This pilot clearly lost control.
Folks, let this story brew--likely the truth will come out as currently everyone is calling the 'OMG the sky if falling', literally. Since the pilot does not have a CAA permit/license shows the lack of knowledge of his tools. As well as the event host for hiring him.
