Looks like https://www.airlive.net/new-footage-shows-an-ukrainian-mig-29-taking-off-from-mykolaiv-seconds-before-the-runway-is-shelled-by-the-russians/ 301 redirects to https://www.airlive.net/new-footage-shows-an-ukrainian-mig-29-taking-off-from-mykolaiv-seconds-before-the-runway-is-shelled-by-the-russians/amp, which is an AMP page, causing a loop.

this STR doesn't properly replicate the problem because we're not redirecting from an amp page to the canonical page
