Not sure is there's some reference here I didn't get. Was there any Americen aircraft named Valentin?
Wikipedia said:
Valentin (French, German, Romanian, also Russian and other Slavic) or Valentín (Spanish) is a masculine given name. It comes from the Latin name Valentinus as in Saint Valentine and Saint Valentine's Day. Valentín is also a Spanish surname, again a form of Valentinus.
Think it's just being a bit punny and switch-a-roo-ey.
