Formation of 3 moving South to North over Mass.

at 00:20, 8 May 10 I observed 3 objects traveling south to north, in formation.....sky was slightly overcast, stars were visible.  The objects appeared as satellites,of which I have seen many, but were in a line abreast formation, and moving at very high velocity, toward Mt. Monadnook, in New Hampshire. They maintained their shape and speed, until passing from my view into heavier cloud cover to the north.  No noise or flashing lights, and not an object breaking up in the atmosphere.
