Unknown craft with string of colored blinking lights in night skyI was out in front of my porch while star-gazing (one of my favourite pastimes). At the same time my dogs were barking loudly apparently for no reason.As I looked towards the Orion belt, I got almost startled seeing a slow-moving reddish-golden blinking light or two. Immediately the blinking light(s) increased in number to around six or seven and pulsed away on and off at a rapid rate from left to right in a straight string-like pattern apparently under the belly of the possible flying craft (which could not be seen due to dark evening though the sky was fully clear of any clouds). The possible craft started heading at quite a fast rate (faster than any normal aircraft) towards north-west direction (opposite to the airport) while the lights continued to blink in changing colors of red, golden, green and blue. Within a minute or so the possible craft silently moved away out of my sight.Living close to the international airport of our capital since last twenty years I have had a good guess and estimation on structural designs of commercial airlines, two-engine light planes and choppers, etc. in flight. But the above described craft with those string-like blinking lights that I witnessed was completely different from any earthly aircraft.
