The logic of some of the threat-deniers baffles me.
Because engine failures from bird strikes are usually contained, we don't need to worry about a drone with lithium batteries being ingested by an engine.
And the plane has another engine anyway...
So carry on playing with your "harmless" toys chaps
Your logic baffles me too. What's so bad about lithium (as opposed to nickel metal hydride etc)? The toys are not exactly harmless either, but those who use them know that fairly quickly. They also know how hard it is to land it within a few metres, let alone guide it into a landing airliners flight path from several nm away.........but you just keep crying that the world as we know will end.
