When people fire off ‘celebration’ rounds they usually are at a high apogee, close to 90 degrees. Meaning they will typically land within a small radius of the person shooting. To reach the speeds needed to penetrate the helicopters’s body the round would have had to be at a lower apogee and thus a purposely aimed shot.
Not everyone has the brains to put that together.
And bullets go so far, that it could have been fired a long distance from where the planes were.
