ASPEN: Emergency car and helicopter by JCC

Here I present a mod where you can have a beautiful ambulance, and amazing helicopters, all fully functional. They even have functional chests

When you have a chest in your hand while you press shift and right click on the vehicle, a chest is added. 
To fly in a Helicopter, the instructions will appear on the screen, for example, with the Z key you ascend the helicopter, and with the S key you descend, with the D key you turn, etc.
