In January 2020, I left for a mission, along with a 75-person crew. I had got to know everyone quite well, which made me feel confident that everything would run smoothly. The main goal of the mission was to voyage through the water, identifying boats and aircraft with our sensors while remaining undetected. We were the eyes and ears of the French navy, 300 metres under the ocean.
Being in a submarine(潜水艇) is a bit like being in a spaceship. Letters from family were allowed to keep crew members motivated, but for safety and caution, all communication from the crew's families was seen first by navy staff who removed any content that could cause panic on board.
In February 2020, as Covid-19 started to emerge in Europe, the navy began to block all Covid-19-related news in our life. Throughout March and April, we had no idea that Covid-19 was even a thing, let alone that France was under strict lockdown.
The day finally came when we were set to come back. The radio channels on the submarine announced the news: "There is a deadly virus, and the country is locked down." Actually, the information didn't make any sense to me at that time. "Lockdown" was a new word to me. I didn't know what to expect.
When I got out of the submarine. I got my phone back and received weeks' worth of panicked messages. I took a train back to Paris, where my family lives, and was completely lost. People had masks and gloves on. I put over my mouth a fireproof mask that had been given to me by the navy. I just thought, everyone is hiding their mouths, so I'll do it, too, even though I didn't know why.
