Last night i was doing an md11 flight to sao paulo. I got the flight plan and saw that another Swiss air had the exact same plan. Of course i copied it to save time. I got up to cruise and went to sleep. When I woke up i realized i passed the other swiss. On reviewing the replay i found that we came within a thousand ft of eachother.
Plane: SWISS MD11
Also here’s a nice pic of the tail reflecting the moonlight.
