Re: Unfortunately it will likely happen
You know what will happen if a drone is sucked into an engine on landing? The aircraft will land and someone will be sued for damaging a very expensive aircraft part. The engines are mostly at idle during approach and landing anyway.
But let's say this happens at take-off. Engine sucks in a drone and poof, engine is destroyed. What will happen? The aircraft will continue the take off, circle back and land single engine. This already has happened- with birds.
And since drones are less likely to be in a flock of hundreds of other drones, birds are far more dangerous. Aircraft are built/designed/tested to withstand these events.
