Hello, on june, 29. 2009 Isaw in the sky over Tallinn, Estonia manouveur I tried to describe on attached picture here:
Can anyone explain it, was it something serious or just some routine? For backround info: there were 2 other planes, one before and one after who flew same route as plane who made such rapid turn on picture, one around 15 min. before and other around 30 later. and they both flew straight, no turns whatsoever but why this one made such manouveur, especially as other plane was on the above shown course?
