Half a minute later, Tasić attempted to call BA476 and instruct it to report passing the next waypoint at Našice, but was answered by a different flight: Tasić continued to call BA476 and JP550, ignoring calls from other aircraft, but to no avail: Meanwhile, a Lufthansa Boeing 737 was travelling eastbound on UB5 at flight level 290 towards Zagreb, only 15 miles behind the Trident.
Pola minute kasnije, Tasić je pokušao kontaktirati BA476 i narediti im da ga obavijeste kada prijeđu iduću putnu točku kod Našica, ali odgovor je dobio od drugog zrakoplova: Tasić je nastavio pozivati BA476 i JP550, igorirajući pozive drugih zrakoplova, ali uzalud: U međuvremenu, Lufthansin Boeing 737 se kretao istočno po UB5 na razini 290 prema Zagrebu, samo 15 milja (24 km) iza Tridenta.
