Dear
Student,
Please find below
the solution to the asked query:

The shadow has two parts umbra which is formed at a very small
distance and is not visible due to unavailability of a screen, the
second part or the penumbra is to large and too faint to be visible
on the ground This is why we do not see the shadow of objects
flying high in the sky
