Yes. The I-16 was the best fighter in the Spanish Civil War until the arrival of the Bf-109B of the Legion Condor

por supuesto sino que se lo digan a mi abuelo en el frente del Jarama un abrazo compañero

¿Tu abuelo fue piloto en la guerra civil?

Your grandfather was a pilot in the war? (traducido por respeto a los compañero que no hablan español)

sorry for writing in my mother tongue and an apology to all those who knew no Spanish is that I came from the heart ..
and if my grandfather was in the civil war as a pilot in the national side but unfortunately I have many memories of him as he died when I was very small.
accept my apology hug and see you in heaven tonight .. perhaps
Forgive my bad English friends:)
