My Sister and I are looking for a movie which we can only remember the ending.
It has to do with a pair of Pilots that don't return. There is a woman in the end of the movie that's on a cobbled street, it's raining she falls into the street crying and when she looks up she sees their faces in the clouds.

When did you watch this movie? Was it an old movie?

Is it Top Gun?

This is a wild guess, as I've never been able to see the whole film, only bits here and there.

Restless Spirits (1999 TV movie)
Amazon.com synopsis:
This gentle, modern-day fairy tale explores a family trying to recover from a father's death. Katie is a combative 12-year-old; her brother, Simon, is almost mute; their mother desperately needs time to rebuild her life. She takes her children to visit their grandmother in Newfoundland. Grandmother Lydia tells Katie she understands that she has "to stay angry or you'll forget him." Lydia says that "some people have the gift of seeing," and Katie and Simon prove her right when they meet Charles Nungesser and François Coli, historical French aviation heroes who disappeared trying to beat Charles Lindbergh across the Atlantic Ocean in 1927. These lost souls repeat their fateful crash into the swamp every time the fog comes in. Katie realizes they must finish the flight to enable their escape to heaven and begins the improbable task of raising their plane from the deep.. . Nungesser bemoans being beaten by a "mailman", while Coli mourns the loss of his wife and child. Resurrecting L'Oiseau Blanc helps Katie interact positively with people and develop friendships. By the magical climax, she learns what inspired her father to be a test pilot.
