Polish flag carrier, one of the world's oldest airlines
Since late June, civil aviation has faced several safety scares: a JetBlue A321 has reported a collision with a drone near JFK and landed safely; a United and a helicopter pilot have reported near-misses with unmanned aircraft near Newark and Manhattan; Delta 1076 reported a firework strike during descent into Chicago Midway; and LOT Polish Airlines flight 155 emitted a false hijack transponder code and was escorted to Burgas before authorities blamed a transponder error.
