It can also be used as a symbol of freedom and escape. In a romance novel, if the characters are in a difficult situation, they can use the helicopter to break free. Say, a couple is trying to get away from a controlling family or a bad situation in the city. The helicopter becomes their means of starting a new life together, flying towards their future. Moreover, during the flight, they can have deep conversations, look at the beautiful scenery below, and bond on a deeper level.
A helicopter can be used to create a sense of adventure. For example, the hero can whisk the heroine away on a helicopter ride to a secluded and beautiful location, like a mountaintop or a private island. This sudden and exciting form of transportation adds a touch of spontaneity and luxury to the romance.
