Find Intersections of a self-intersecting polyline feature

Hello,

Dataset:
- Shapefile with multiple polyline features representing flight paths. Features intersect each other and some intersect themselves as well.

Task:
- Find and create a point at every line cross point (intersection)

Current Solution:
- Use the "Intersect (Analysis)" tool to find the intersections and save a point at each intersection.

Problem:
- The intersections of a feature with another feature are found but the intersections of a feature with itself are not found.
- See the attached image for an example. The selected item is a single polyline feature in the shapefile.
- The tool finds the points shown, but not the self-intersections.

Ideas? Many Thanks!
