Pulling in the direction of part of the aircraft (6)

I believe the answer is:

towing

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

'pulling' is the definition.
(thesaurus)

'in the direction of part of the aircraft' is the wordplay.
'in the direction of' becomes 'to'.
'part of the aircraft' becomes 'wing' (I can't explain this - if you can you should believe this answer much more).
'to'+'wing'='TOWING'

Can you help me to learn more?

(Other definitions for towing that I've seen before include "Recovering from breakdown" , "Pulling along (a car)" .)

I've seen this clue in The Irish Independent.
