Almost nothing. July 4, 23:30z HAWG 1 (2 x A-10, Fort Smith) depart for pre-fireworks fly-by around 01:00z over downtown Fort Smith. Otherwise I saw a Chinook and about 3 Blackhawks near the airport on July 4 around 19:45z while I was at a cookout, but did not hear them on my recordings. Collins Fort Smith, Arkansas
