BOSTON -- It was a rough and weary night for passengers who thought they were headed to France Tuesday night.

First, their red eye flight bound for Paris was delayed taking off by two hours.

Then, less than a half hour into the flight they were forced to make an emergency landing at Boston's Logan International Airport.

The plane returned to Logan about 2 a.m.

Passengers aboard Flight 321 said they were told the plane was having technical problems.

There had been some initial reports of engine problems but, so far, no confirmation from the airline or MassPort.
