Stationary light for several minutes (far away), takiing off suddenly at great speed.

I was 24 or 25, never heard of UFOs, lived a block from Northrup Aircraft co. and was fascinated by the huge 6-engine bombers (engines on back of wings), and could feel their engines ahead of them being visible. I was always watching the sky. 
I saw this "star" in a bright Calif. day and watched it, getting a 'bead' on it using telephone lines.  After a few minutes, it suddenly darted off, very fast, faster than even the jets Northrup was testing. 
I must add that it was quite a distance off, as one can tell by how the eyes feel with focusing either near or far away.
I decided this should be known by someone other than me!
Witness indicates that the date of the incident is approximate.  We have assigned an arbitrary date in June 1954.  PD
