Cascina Vaga was an old airfield that disappeared completely after the war.
I know it well since I used its area as a gather point for the reunion of 2° Gruppo Caccia pilots and members which I organized back in 1989 and which saw all those incredible boys reunited together for the first (and unique) time.
It is a memory that I still cherish...
Here it is a map where the former airfield area (no runways, only grass surface) is evidenced...
P.S. the area is east of Stradella and south-south-east of Arena Po
