Objects disappearing in different views and renders

I’m tearing my hair out. I have a scene with a few objects however some are visible and some aren’t…

All the objects are visible in one view, however if you open new views the nosecone and propeller objects disappear. regardless of the 3D view type (Wireframe, Solid etc)

These objects also don’t render.

What am I missing!?!?!


The view with the propellor is in local view rather than a global view in all the others views. Change that view back to global (numpad/) and see if that helps. Supply a link to a blend file for further assistance.

Doh!

(numpad/) did indeed reset the other views!!!

Thanks!
