DJI has a number of good points, and as a company I understand their desire to defend their products and their brand. For me, the issue is outside of what is seen in the videos. A drone crashing into a plane or helicopter is dangerous, period - so making efforts to avoid it is of course necessary... however the first thing that came to my mind wasn't about the damage done by the drone itself - what about the battery(ies)? What happens when a lipo battery smacks into a wing full of jet fuel? What's the worst case scenario there? Is that a topic of debate or engineering approach to make the unlikely event of a drone striking a plane or copter less likely to be catastrophic? is it even possible for a sudden fire/explosion/ignition incident? The batteries would undoubtedly be smashed to bits, with all sorts of potential chemical & metallurgic reactions, etc. Fire only needs three things to exist, air fuel & a spark - and a drone hitting a flying vessel could certainly complete the three. So I think this topic is necessary and important - but is the discussion going in the right direction?
