This made for TV movie (1991, Showtime) was never released on NTSC DVD. It was released in PAL territories under a slightly different name (Flight of
the Black Angel). The only available NTSC version is VHS. And I'm pretty sure it's on YT, also.
It's my second favorite made for TV movie (after Purgatory). I'm not sure a blu-ray release is economically feasible, since I'd probably be the only person to buy it.
