For all those interested, I received a phone call about 15 minutes ago
(9:15 approx.) and was told to look into the sky for 3 erratically
flashing objects holding stationary position in the sky. From my
position in Greenland (minimum 9 miles away), however, they crossed
about 30 degrees horizontal arc over those 15 minutes. I haven't done
the math yet to determine speed, nor have I yet received the details I
need to triangulate elevation, but whatever they were, they were not
airplanes. Very cool, and thanks for the call!
