"MIRABEL -- An Air Transat plane had to return to Mirabel Wednesday morning shortly after takeoff after experiencing engine problems.
A witness said one of the three engines of the aircraft, a Lockheed 1011, appeared to be vibrating. In response to the problem the pilot turned off the defective engine and turned back to land at Mirabel.
The aircraft, which was headed to Port-au-Prince, Haiti, discharged a significant amount of fuel as a precaution before landing without problem, around 9:15 a.m.
One hundred and forty-seven passengers and 14 crew members were on board"
