Need help with a "scripted event"!

So, I want to recreate the intro from Opposing Force, when you are sitting in a helicopter and i already made a portion of it (see GIF below):

Now, what I want to do is a "scripted event" where the chopper goes down just like in the game.

I had the idea of having two (scripted) monsters walking towards a line. When the first monster would cross it would be teleported to the helicopter where the player is located, however the sprite of the monster is changed to an sprite of an explosion. Now when the second monster would cross a line (about 2 seconds later), it would end the level.

And heres where you come in! Yes you! So help me(if you want to...).

Any sort of help on how to make this crazy idea work would be more than appriciated!

Thanks,

So, I absolutely have no idea how to help, but I felt it was necessary to mention that your username is absolutely perfect.

Thanks man. 

So, just a quick update!

I found out how to do it and it actually works!

First I made this:

And then I did this:

Woala!

I wonder if anybody else has done something like this!

Rather than having a thing on a conveyor belt cross a line, it would be easier and "cleaner" to make an OPEN script (launches automatically when the map starts), call Delay in it (waits given amount of time), and call your intended sector action special(s) after that Delay.
