hello
We just had delta/northwest and KLM "racing" so it gave me a good chance to test our 3D.The DAL264 A333 was at 35000ft 499kt and the KLM was at 41000 and 492kt. I got the 2D shot when they had just passed and the 3d at around 50NM. I know it is common to get two aircraft at that distance where most of you are but it isn't here.
