What do you mean? The aircraft is Sofia, the flying IR telescope. See https://en.wikipedia.org/wiki/Stratospheric_Observatory_for_Infrared_Astronomy and https://www.nasa.gov/mission_pages/SOFIA/index.html The route looks a bit peculiar, more turns than what I've seen Sofia usually do.
should have been a bit more clear, but yes, that is my question. i know SOFIA usually picks a path and sticks to it, not all these turns.
