"GET /static/flightmap.html HTTP/1.1" 404

For some reason when I try to start the Flask server, I get this error:

ubuntu@packer-ubuntu-16:~/userdata/upair/map$ python app.py 
 * Running on http://localhost:5000/ (Press CTRL+C to quit)
127.0.0.1 - - [12/Feb/2017 17:12:28] "GET / HTTP/1.1" 302 -
127.0.0.1 - - [12/Feb/2017 17:12:28] "GET /static/flightmap.html HTTP/1.1" 404 -
127.0.0.1 - - [12/Feb/2017 17:12:28] "GET /favicon.ico HTTP/1.1" 404 -

I tried to run it from the root (upair directory) and from map, and it still gives 404 errors, despite the file existing.

I could also get the file to display by running python -m SimpleHTTPServer 5000, but of course calls to /now don't work because of that, so no planes are displayed.
