Re: Could a drone hurt a 737?
From someone that IS a pilot.
First of all, the Airbus that went into the Hudson had multiple bird ingestions into each engine. Unless the 737 flew into a "flock" of drones, it would only take out one engine. Even on short final, a 737 is quite capable if performing a go-around on a single engine. There is adequate rudder authority to counter the asymmetrical thrust.
As to damaging a control surface, that's very unlikely. On short final, with full (or nearly full) flaps and leading edge slats extended, the airflow would likely push the drone away from most of the control surfaces. A bird strike to control surfaces rarely makes an aircraft "uncontrollable".
Hydraulics are inside the wings and fuselage, and are generally routed through well protected areas when possible. Aircraft designers are not idiots. Again it's extremely rare for a bird to make it deep enough into the wing or fuselage to get to hydraulic lines.
And lastly, if hitting a light plastic drone can damage a landing gear strut (or tire), I wouldn't try to land 45,000 Lbs of aircraft traveling at 130+ knots on it. The loads on a landing gear at touchdown are massive!
As for the other items "Or even if it wasn't landing, it could damage the nav or weather radar. Or break the pitots which detect airspeed (giving you no idea how fast you are flying)", if the aircraft isn't landing, what the hell is it doing below 400 feet?
As a pilot, I'm not defending what this drone operator is doing. There a plenty of things that can kill us pilots, we don't need idiots trying to kill us with their drones!!
I just thought I should shed a little light on reality, not what someone who plays a little flight sim on their computer thinks...
