I volunteered at an elite trial over the weekend. It was at a public safety training center that had some really cool search areas. One of them was a jet! Unfortunately, I didn't have a great view because of the tight area, but it was still really neat to see! All the dogs did a great job, including navigating the very steep and open stairs to get in. This is definitely on mine and Newtie's bucket list now!
ETA: There were five hides in total for this search. The search area included the coach/first class seating all the way up to the cockpit. Most teams seemed to get four, which isn't too shabby at elite!
I saw the video walk through for that on FB. It was really cool, and a pretty large area.
