they've tried about everything so far. RC, ultra lights, mini submarines, semi submersibles, tunnels, magnetic boxes slapped under cars used by people that never get checked, tunnels, throwing it over the fence, and now multirotors. Their choice of airships was unfortunate. It prolly did a flip of death shortly after launch
What the heck, they can afford to buy a few 10 thousand or so more...
The problem is they don't care about the law, only of getting caught breaking it. Unfortunately they seem to have a large enough customer base to make the risk worthwhile.
