He said he did not know who parked the jet.<br> <br> The accident was reported at 8:50 a.m. along World Way West, at the western end of the airport.<br> <br> Officials at the scene said power would be shut down at several buildings and traffic lights in the area so the lines could be removed from the aircraft.<br> <br> Heavy equipment was being brought in to tow the plane back inside the airport.<br>
