My grandmother or my grandfather might have boarded one of these ships. Emigration is big business. It was legal to go to the United States, so my grandparents could travel ( separately; they weren't married when they left Sicily) in safe, steel ships instead of on rubber rafts or in unseaworthy fishing boats like the ones Africans must use to get to Sicily, because European push-back laws force refugees to arrive clandestinely and put them at the mercy of ruthless traffickers.
