How did the task of "the last flight of Toreno" in San Andreas pass?

It is skillful to finish this task. Although you can ask others for help, you will feel more fulfilled if you can do it yourself.

First of all, before completing this task, you must ensure that your blood volume and armor are full, and you must kill all the enemies next to you before you can get on the tarmac. Remember not to lose too much blood. Get on the tarmac and get the bazooka. Kill the enemy (one or two) next to the motorcycle with a choke. Then use the mouse wheel to quickly switch to the rocket launcher, get on the bus and rush all the way to the bridge. Be careful not to roll over. Soon you will see the helicopter and rush to the bridge. Don't get off the bus. Jump out of the car before you live again (be careful not to get out of the car, or press the F key when the car is still moving), and turn on the sniper mirror after a few rolls. At this time, the helicopter should just come from behind. Don't hesitate to slam, don't be stingy with ammunition, you can shoot it down with one or two rounds, and then go to work.
