Ok, I may have been a little harsh myself there.
You are in fact asking for a walk in helicopter like the one shown in the video, simply associating the player with this wont allow you to achieve what you want.
First off to use the model you need it to be dynamic, the only collision dynamic entity's have is box collision, so the only way to enter it is to turn collision off in the script, if you do that you wont be able to enter it without passing right through it.
There is a reason why lifts are simple platforms that have no walls, at best they raise you in a tube created from segments.
Lift platforms use raycasting to determine when the floor has reached the top level of said segment tube otherwise you will just keep going.
If you really want an insight into how how
easy or difficult it actually is to create a realistic walk in entity with walls and doors or a helicopter as shown in the video, download this and take it apart.

I think you will find this to be a complete one off and its never been done before or since.
I just need you to understand what your asking for (its a combination of models and scripts)and why I found your response to be flippant with how it would be easier than I said.
Even if the chopper is a little more simplified than the elevator its based off it and
not as simple as it appears.
