Not enough being done to curb delinquent droning. Having had an extremely close call with one at 800ft agl whilst in the cruise there was absolutely nothing I would have been able to do to take avoid action let alone spot it in time to do so.
Drones don’t move in a way that we’re used to like birds that change aspect in flight. A drone can just sit stationary in the air and with little to no relative movement can be impossible to spot at any stage in flight unless above and silhouetted against the sky.
