Five objects in sky around LaGuardia airport, N.Y.C., daylight.

I was on break when i noticed a bright point of light (silvery)in a northern position over LaGuardia airport. The object was stationary.At first I thought it was a satellite in a polar orbit.
After maby five minutes two other objects came into view taking up a triangular formation. It was like light reflecting off a metal surface. The light was flickering and then the two other objects were in focus. The objects remained in a stationaty position.
A few minutes following this two other objects also appeared to the east of the three objects. The position of the three objects was to the west of the airport and the other two to the east of the airport.
Within fifteen minutes the first object left the formation and moved in a southern direction. The speed of the object was slow as if it was taking it's time with, the remaining objects holding their position.
After whatching the moving object I looked back at the remaining objects and another object took up the position to form the triangle with the formation now smaller. Following this cloud cover moved in and I lost the oblects above the clouds.
At the time of the sightings the sky was clear with unlimited visibility. So, the objects stood out against a clear blue sky. Thinking about it now it seems as if the objects were entering our atmosphere and appeared to be under intelligent control.
Witness indicates that the date of the incident is approximate.  PD
