I happened, serendipitously, catch a trailer, on PBS, and knew, at once, that I had to watch this. Everything I like — all-things-British, period drama, innovation, aviation — in one movie. I have set the DVR to record.
Up here in the Northeast it is on Boston WGBH Channel 44 — their auxiliary channel to the main Channel 2. You will have to check the PBS listing in your area. It is at 8pm on Thanksgiving — Thursday, November 22, 2018.
Given that it is BBC produced it is bound to be superlative. The BBC, as YOU know, rarely lets the side down.
