B767 of LOT Polish Airlines heading to Newark (EWR) had to abort take-off after a technical failure was disclosed when the jet was already rolling along the runway in Warsaw. Flight LO 15 scheduled for departure on Wednesday was eventually planned to depart on Thursday at 11:30.
In the last few weeks LOT long-haul planes have seen a series of technical troubles. Last month B767 flying from Chicago (ORD) to Warsaw got into turbulence and had to perform emergency landing in Toronto. Last week B767 was held at JFK for two days after a failure in cabin pressure and A/C.
