Found this while browsing Disney Plus and decided to give it a try, particularly as it's directed by Iain Softley who doesn't get nearly as much credit and recognition as he deserves (does anyone remember the excellent K-PAX for example?).
The movie draws us steadily into the story and maintains a mostly quiet and thoughtful atmosphere yet with some tension when required.
Not only did I enjoy the story but the visuals too - I am going to assume that the outside views of the aircraft when flying were CGI and not physical models with CGI 'enhancements', etc and, if so, they were very well created with a good sense of realism.
In summary: I enjoyed it a lot - despite the relatively short running time it never felt rushed.
Recommended.
