Dear Mr. Pavlov,
Thank you for posting your request on History Hub!
According to articles published in the Washington Post and the New York Times, ABC News’ “Good Morning America” included a five-part series titled “Ron Reagan’s Russia” during episodes aired November 16, 1987 through November 20, 1987 that may include his visit to Pskov Caves Monastery. We suggest you check for recordings of “Good Morning America” episodes at your local public library.
We also suggest that you contact the University of California Los Angeles Film and Television Archive Research and Study Center (ARSC) regarding their News and Public Affairs Collection via email at firstname.lastname@example.org as their online database indicates they hold a substantial number of episodes of “Good Morning America” programs from 1987; and the Vanderbilt Television News Archive, 110 Twenty-first Avenue South, Suite 704 Nashville, TN 37203.
We hope this is helpful. Best of luck with your research!
