Archon<>Procyon another maneuver you could have taken with the plane heading directly for your drone would have been the CSC (Combination Stick Command). Sure, your drone would have dropped like a stone straight into the lake. I'd say that given you couldn't have predicted whether the plane was about to change attitude and strike your ascending drone, the CSC would have been the better choice but I realise that in situations like these there's no time to assess options and the reactions have to be automatic.
