How should the "under\nether" chapters end with?

I was wondering how does that chapter end in the beta. In the retail version Route Kanal ends with the player reaching the airboat, but how it would work in the beta version?

We know that the 2003's maps are similar to the retail one, finishing with the airboat, I think.

But what about the 2001 or 2002 era? Did it end directly to the Wasteland, or to somewhere else? Also, was the concept of using a jetski/airboat already there?

Yes, I know that the leak is unfinished, but I would hear your opinions about it. Like how you think it should have ended.

Gordon Freeman would have to get outside the city. We would see a huge concrete wall that surrounded the city 17. Further, we would advance along the canals of an abandoned part of the city. We would meet headcrabs, barnacles, houndeyes, bullsquids and manhacks along the way. Combine soldiers and metrocops would shoot at us from above, and they would also be supported by helicopters. Sometimes, we would see citizens hiding in shelters.

Initially, the developers had no idea that the player could control any transport. The idea of controlled transport came to their minds around the end of 2002, after rethinking the plot.
