Range and altitude for missiles is not the same. The max altitude for a stinger at that time was only ~13,000 ft.

They didn't get the settings for their PID controller quite right. Too much overshoot, not enough dampening.

The Iranians pride themselves on building a lot of their own stuff. This is possibly an indication of their quality of work at the time.

Even our stuff sometimes tracks a little screwy.

Look at the flight paths of some of these Iron Dome interceptor tracks.

ZigZagging is something that occasionally happens when you are trying to intercept a flying object especially as the missile gets closer to it's target and has to correct faster.
