Pau is an partly military airport and there is a lot of parachuting action and there have been a lot of dutch C-130 movements as well over here.
The French Tigre helicopter is a regular helicopter to be seen here.
The only airworthy Noratlas is also a regular visitor wich does paradrops as well for the military.
Best part of the day for spotting is mostly in the afternoon when it is sunny due to the position of the runway .
Off airport there is an museum for the french parachute regiments and they have an Noratlas and Puma on display outside.

Aircraft departing here are seen on adsb or flightradar24 as departed from PUF/PAU airport but the fields are an aproximate 10 kilometers apart of each other.
On this particular day they flew a lot of military parachutists sometimes the Twin Otter operates from here as well.
