I get very scared when the plane jumps around in the air.
Once when I was flying from England to New York, the plane dropped about 5000 feet in seconds; everything flew everywhere. I am scared since then that the plane will fall out of the sky.
I'm currently trying to avoid flying on the A380 but an upcoming flight might require it. I am concerned that economic concerns on the part of Airbus are trumping real safety issues which have come up with this plane - engineers seem to agree there is cause for concern.
