It's within my top ten and is the one that most often comes first to mind. I'll use some excerpts from Wiki which express better than I can.
Two main reasons for being a favorite;
Lots of good flying scenes using some old warbirds, and other iconic aircraft.
Addresses the concept of existence after a physical life, with a view similar to my own on the subject of soul immortality.
"Always"
...
Always is a 1989 American
romantic fantasy drama film directed by
Steven Spielberg, and starring
Richard Dreyfuss,
Holly Hunter,
John Goodman,
Brad Johnson and
Audrey Hepburn in her final film role.
[3]
Always is a
remake of the 1943
romantic drama A Guy Named Joe, which was set during
World War II. The main departure from the 1943 film is the changing of the setting from wartime to a modern
aerial firefighting operation.
[4] The film, however, follows the same basic plot line: the spirit of a recently dead expert pilot mentors a newer pilot, while watching him fall in love with the girlfriend he left behind. The names of the four principal characters of the earlier film are all the same, with the exception of the Ted Randall character, who is called Ted Baker in the remake, and Pete's last name is Sandich instead of Sandidge.
...
Pete flies one last mission, despite Dorinda's gloomy premonition. During the fire bombing run, Al's engine catches fire and is about to explode. Pete makes a dangerously steep dive and skillfully douses Al's engine with a fire-retardant
slurry, saving Al. As Pete struggles to regain control from the dive, he flies directly through the forest fire, igniting his own engine and causing the aircraft to explode.
Pete strolls through a burned-out forest. Coming to a small clearing, he meets Hap, who explains Pete died in the explosion and now has a new purpose: As spirits did for him during his lifetime, he will provide
Spiritus ("the divine breath") to guide others who will interpret his words as their own thoughts.
Although time is non-linear from Pete's perspective, six months have elapsed in the real world and Al wants a grieving Dorinda to move past Pete's death. He takes her with him to Colorado to work at the flight school where Pete was to command pilots who will be training to fight fires, one of which is Ted Baker. ...
