(CNN) -- "Nine hours down, 150 to go."
It seems like any run-of-the-mill Facebook status update. But what its poster, Matt Guthmiller, is attempting is anything but run-of-the-mill. The 19-year-old is on a solo flight that he hopes will take him around the world.
If he completes it, he will become the youngest person ever to do so.
The "9 hours down" referred to the time it took the MIT freshman to fly Saturday from El Cajon, California, to Aberdeen, South Dakota, the first leg of his odyssey.
The "150 to go" marked the remaining hours he plans to fly over the next six weeks on a plan that will take the South Dakota native through Athens, Cairo, Bangkok, Hawaii and more.
If successful, Guthmiller will replace Barrington Irving as the youngest pilot to circumnavigate the globe alone. In 2007, the then 23-year-old Irving accomplished the feat in 97 days.
On Monday, Guthmiller flies to Teterboro, NJ just outside of New York City, according to the flight itinerary he posted on his website.
If all goes as planned, Guthmiller will land his 1981 prop powered Beechcraft Bonanza back in Aberdeen on July 12th -- just 42 days later.
