OnCollisionEnter2D, all objects above box collider(not touching) are destroyed

Questions & Answers

I have a box collider around a 2D small airplane. Everything that touches the area around it of course will destroy itself…

However, everything that floats above the collider on the Y axis also destroys.

Has anyone else had this issue?

public class PlayerScript : MonoBehaviour {

	void OnCollisionEnter2D(Collision2D coll) {
		if (coll.gameObject.tag == "Enemy") {
			Destroy(coll.gameObject);
		}
	}

Problem mysteriously solved itself after turning off a bunch of script and re-enabling them.

no idea.
