Two Qantas planes land during a number of incidents

Four flights turn back to airport since A380 incident from in-flight problems

SYDNEY - A bird and a bolt of lighting were the latest problems to strike Qantas, the airline said on Wednesday, causing the fourth flight turnaround since an engine blowout on one of its Airbus super-jumbos caused a global safety scare.

The string of incidents on Qantas' older fleet of Boeing planes is unrelated to the A380 scare and were caused by various glitches and uncontrollable events that are not uncommon to any major carrier, the airline and a commercial aviation analyst said. But they were drawing extra attention following the super-jumbo blowout.
