On July 4 last year, Lachlan Smart from Australia took off in a Cirrus SR22 aircraft and completed the history-making journey at Sunshine Coast Airport, Queensland, Australia on August 27, aged just 18 years 234 days.
The announcement comes after an extensive evidence review process that involved checking the GPS data for the entire journey, all take-off and landing times, multiple witness statements and video footage, the Guinness World Records said.
Smart stopped in 24 locations in 15 different countries during his seven-week flight, and covered 45,000 kilometres.
The previous record holder was Matthew Guthmiller from the US, who was aged 19 years seven months 15 days when he achieved the title back in 2014.
