Does this video prove that 30 British aircraft intercepted Russia's Black Sea fleet? No, that's not true: The video shows a compilation of file photos, some not even of British aircraft, with subtitles. At least one shows an obsolete aircraft.

The second image is likely an American-made, McDonnell Douglas F-4 Phantom II, originally developed by McDonnell Aircraft for the U.S. Navy, which saw combat in both the Vietnam War and Operation Desert Storm.
