What came first, Cessna’s Conquest I or Conquest II? Plane spotters with a taste for twin turboprop trivia testify that in this case, the Cessna 441 Conquest II predates the Cessna 425 Conquest I. If you spot a pressurized twin that looks like a piston-powered Cessna 421 Golden Eagle that on closer inspection is obviously a turboprop, go ahead and identify it as a Cessna Conquest I (although there is a small chance that it’s “just” a turboprop-converted Golden Eagle). Before being renamed, the Cessna 425 was called the Corsair.
