Seeking Anime, don't know which one it was..

[nothing left]

Hello,

I don't know if this belongs here, but i also don't know who else to ask.
I am searching for an anime which i have watched years ago.

The story is about two kids flying a plane, and delivering mails.
I think the kids were siblings? No sure about that.
The father did the same job, but went missing years ago. At the end of the video, the kids find the faters plane, including a high priority mail.

Does anyone know about this Anime?

Did you already skim through this list? https://www.anime-planet.com/anime/tags/aviation

Is this Last Exhile?

I haven’t seen it in like ten years so I don’t remember for sure.

I don't know how I saw this when it was originally posted and didn't immediately think of Last Exile.

Which I still need to see, or at least skim enough of to make an AMV with "Where No One Goes".

Yes, it's "Last Exile"!

Thank you guys
