youtube-dl works on almost every NBC Nightly News video, except for this one

I've looked into this (but still am inexperienced in opensource). Here's my findings:

• I replicated the bug: this url does not download.
• I found the url that contains the video data: https://msnbc.vo.llnwd.net/l1/video/h264/2017/low/nn_netcast_180306.Copy.01.mp4 this does work with youtube-dl.
• I found a way to get this url from the page's html: there's a <script> within the body of the page where
  var playlistData = {...}
  to get the uri from the json data: root.video.guid, which is "nn_netcast_180306.Copy.01.mp4"

But...

[sutt]

Checking yesterday's news today, it appears youtube-dl works:
https://www.nbcnews.com/nightly-news/video/video-shows-inside-southwest-plane-before-emergency-landing-1215017027899

I'd recommend testing a few more times and if it continues to work then close it.

Multiple current videos are working on nbcnews.com

If it's worth it: we could add more error handling in parsing / better error message during "downloading JSON metadata" phase where this breaks*. Not sure if this is worth it, could someone advise?
