Here's what your data looks like:

Looking deeper into it, the drone was hovering and holding position, with all indications perfectly stable and the data just stops...
It's always easier with a short description of what happened or what you observed.
But here's what I make from the data.
It looks like you launched (without waiting for GPS or to have the drone record a home point) and climbed to about 15 feet...
Never mind all, I guess I should've looked at the log first.
Data shows IMU altitude of 37.1 ft. when RTH was initiated...that explains it. I just don't remember it being that high...getting old, I guess.
