Can anyone identify these two tree's please ?

Hey ,

Can anyone do me a massive favor and identify these two tree's for me ?
the larger one is around 40 - 50 ft high and releases helicopter kind of seeds every autumn and the second one is in my courtyard, its branches are very thorny and the leaves are small and leathery.

Thanks for any help.

1) Sycamore
2) Is it thorny? (if so possibly Pyracantha)

 

Pyracantha has the right leaves for it.

 

But I couldn't see any berries.

 

Pic three you can see berries top right by the window

This reminds me, need a Pyracantha for the garden. Thanks Alex
