When my family visited the Alpine Tunnel this summer, I rented a drone hoping to get great aerial footage of the west and east portals. I ran out of time on the west side and, due to my inexperience with drones, was too afraid to fly too high on the east.
Lo and behold, I found someone who did what I wanted to do at west portal. He flies his drone super high! It's so high that at one point you can even see the eastern approach. It is stunning footage. I don't know who David Moore is. This video simply came up in a Facebook search for the Alpine Tunnel. I wish his video was on Youtube, but I could only find on Facebook. Here
is a post with some screenshots of his video and a link to his video.
