The LOT photo was taken in bad weather. Considering the plane is quite common in the database it means that acceptance criteria are high for these pictures. Overall the picture quality is reasonable, considering the conditions, but it could be sharper.
The same goes for the Austrian F70, although it is a bit better. I do not like the angle of this shot, but this is personal. Don't waste film when there's no sun. In my view there's little you can do to make these shots better, simply because you need sun to make them shine!
Hope this helps.
