Might the last example of HD's list have been a satellite in geosynchronous orbit ? Perhaps even one of those 'nosey' ones that peek over our shoulders ? The pulsating of the light might have been the solar panels and/or antennae moving ? I certainly have seen a satellite or two in the daylight before, actually the ISS and that American spy satellite that came down through the atmosphere a year or two ago (by complete chance).
The other of the attacking light from the desert...... that must have been freaky, especially as it was plausible that the USSR might have been the attacking 'aircraft'. Were there any 'experimental' or secret aircraft at the time that might have been under test to see how they might fare in war conditions ? Obviously with the passing of time such information might have come to light contained in released records.
Any thoughts gents ?
