"Jet airplanes for sure are completely safe from small drones."

That feels like a bold and unsupported assertion. Ask a pilot how they'd feel about takeoffs or landings through airspace filled with adversarial drones.

A flock of unlucky geese can knock out a jet turbine, how is this a "for sure" conclusion?

Until they land then, due to their cost, they become a very juicy target to aim for.

maybe in the air, but I seem to recall the Ukrainians being successful at attacking Russian planes on the ground.
