Lightning has struck an incoming international flight. Engineers assess the damage, as passengers become increasingly impatient. High winds lead to runway closures, adding pressure to flight schedules. Another plane arrives with potentially dangerous liquid leaking from its cargo, while three ground crew who came in contact are quarantined until fire services can identify the liquid.

Sydney is experiencing one of the rainiest seasons on record. With violent storms closing down two runways, an incoming flight relays a distress call to the Integrated Operations Centre. A man has suffered an apparent heart attack on board. Will the plane be able to land in this weather? Later, a fire training drill turns into a real emergency as an on board fire is reported from another plane.
