air-miss

air-miss
 n.— «The incident has been called an “air-miss,” distinct from a “near-miss,” which in aviation parlance means the aircraft were on collision course. They did, however, come close enough to breach set norms of lateral and vertical separation.» —“Mid-air scare for Sonia plane” by Sidhartha Roy Hindustan Times (New Delhi, India) Sept. 18, 2007.
