I think there is a misunderstanding here.
The problem with RAK is not the lack of radar alone. Lack of radar is not uncommon all over the world.
The problem is that they have controllers with extremely low knowledge of english (for a controller) AND there is one person operatng the positions of ground, tower and approach (procedural) at the same time.
If you add the ever increasing traffic, the T-37s AND the lack of radar, the mix is quite volatile.
