Hi experts :)

I saw a movie about 30 years ago about what I think was a story centered around
A airplane test pilot... They wore trying to fly very high but the lack of oxygen or
Freezing kept killing them until the hero menaged to write down on a notepad what was happening before crashing
Very old movie (I think)

Thanks
