I managed to get a small tour and take some pictures in KPUB tower. KPUB used to be a small quite class D airport where controllers retired. Then Doss aviation arrived there and things changed....

Small tower.

A long stairway going up (down).

Here's main equipment of controller; radar, wind direction instrument and wooden tracker with cards. Ground would give a card to whichever controller is responsible for runway. That controller would move card around depending on location of aircraft. Note: this is special procedure for this tower only...

Good visibility from up-high

A rare visitor; a large jet with convicts.

Jet is going to 35 past mighty DA20C that are doing run-ups

Another rare sight; military choppers. They went right under patter and made controllers make few comments regarding 'cluelessness'
Hover taxi.
