Series of star-like lights traveling the same path and then disappearing

I saw what I initially thought was a satellite traveling through the sky - it was a light almost like a star.  It wasn't an airplane - it didn't have any flashing lights, there was no sound and it was much higher than an airplane.  As I watched it travel for about 20 seconds, it suddenly disappeared.  I then looked around and saw a series of exactly the same star like lights traveling in the exact same path from Northwest to Southeast.  There were approximately 5 of them, traveling in the same path, the same distance behind the next one and each of them disappeared as they reached the same location in the sky.  The entire process lasted approximately 1-2 minutes.  They must have been traveling extremely fast - much faster than an airplane would travel to cover as much distance as they were covering in that amount of time.
