The quoted news article was a bit, well, too sensational. The acft didn't abort the takeoffrun (twice) nor did they evacuate. First they just did not takeoff as they had a wrong flaps indication, mx fixed it, they wanted to start again but as the flight was scheduled for early in the morning a flight attendant felt unwell, probably didn't eat anything meanwhile - can happen. So they didn't takeoff the second time as well. Both times the pasengers disembark normally at the gate.
Thats the rumours i heard - and far more realistic.
Of course the plane flow safe another leg with different passengers as there was nothing wrong at all.
Offtopic: I so so hate to fly those brandnew fresh out of the factory planes. They always have misindications alot. If i experienced anything in the last few weeks (RA failure and stuff like that) it was always on planes with less than 1000 hrs on the clock. Is there a special thread for this topic somewhere?
