Helicopter and Plane Challenges - Bet You Can't do this

Here is a fun post. I've came up with a few challenges for you to try and do with a helicopter.

With a Helicopter

1. Fly under a bridge 
2. Land in the restricted area 
3. Take off in one of the helicopters located in the police departments 
4. Kill pedestrians by using the rotor blades. 

With a Plane 

1. Fly under a bridge 
2. Fly upside down in the hydra metres from the sea and then get back up without crashing 
3. Do a barrel roll and loop the loop in an AT-400
4. Land a Shamal in Grove Street
