It happened often in the years to spot Flying bombs emitting lights from a clear (unlike in the case of ionization phenomena) and data collected through the various testimonials we infer the following points in common: they can have lights and coming from Both from the surface and in almost all cases they are intermittent when the airplane is in a state of quiete and Fixed when in moto . These sources of light seem to have a close correlation with the propulsion system , Especially in UFO-shaped zone , Called Flying Cigars .
Prototypes smaller, long 5 or 6 meters and is usually spotted on the ground, were at the extremes of top , Symmetrically distributed from the 4 rectangles leaving a filter white light similar to that of a very intense neon .
The models of much larger (around 30 meters long and fusiform almost always) have the same type of lights but they are located, rather than above, along sides Often spread over more files Over 4 or 5 light sources for each.
As for the color you notice that the windows give off more light power blue while those from the extremities of it out green .
