The airflow would be trying to prevent a collision with the front of the wing, and a drone would simply go where the wind blows. Which is to say if a drone flew straight for an airplane wing, it would fly around the wing and suddenly explode in the massive turbulence behind the wing. This would look very surprising because to the naked eye there is nothing behind the wing.

Hitting the fuselage, or entering an engine is probably more realistic. Both would be expensive, but won't be a threat to the passengers. Maybe hitting the wingtips would be doable ... not sure.
