In the radiotelephony book, I met a conversation as follow:
Controller: American fifteen seventy -two, you're five miles from MISTR. Cross MISTR at or above 3500,cleared for VOR runway 15 approach.
Pilot: OK we'll uh, we're cleared for the approach. And we'll corss MISTR at or above 3500, American fifteen seventy-two.
The question is: What does MISTR stand for and what is it ?
