Land one flying, over the radio (6)

I believe the answer is:

russia

I'm a little stuck... Click here to teach me more about this clue!

'land' is the definition.
(I know that Russia is a land)

I don't understand the remainder of the clue.

(Other definitions for russia that I've seen before include "Moscow's country" , "nation" , "Country where Omsk is situated" , "Putin's country" , "US air's bad in this country" .)

I've seen this clue in The Guardian.
