Its presumably faster than running away (6)

I believe the answer is:

flight

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

'running away' is the definition.
(flight is a kind of running away)

I can't explain the rest of the clue.

(Other definitions for flight that I've seen before include "Aviation" , "Exodus" , "Journey made by plane" , "Attachment to missile < part of Air Force" , "The feathers on a dart or arrow" .)

I've seen this clue in The Irish News.
