Crossover challenge:

Here's the premise:

Team Time is going to do an ep in the US - in the southwest where a few artifacts suugest a possible ancient civilization. They fly to Kansas, then charter a small plane to get them and their equipment to the site.

But

They have to make a forced landing in ... Schuster's Field.

Testing their equipment, they find some interesting geophys readings and so decide to investigate. And....

So any takers?
