One of the Hunter Brothers doing some mid-air mechanical checkups on their Stinson SM-1 Detroiter during their 23-day-long flight without landing in 1930
Ninety years ago on June 11, 1930, the four Hunter brothers began their journey to break the world record for Duration in an airplane with a flight that was to last an incredible 23 days.
The roles of the brothers were defined as follows: John and Kenneth were the pilots of record plane the City of Chicago, while Albert and Walter worked as the refuelling crew in the Big Ben. Together, they remained airborne for 553h 41m 30s, on a distance equivalent to one and a half times around the world.
Taking off from Sky Harbour Airport, USA, on June 11, the City of Chicago, a Stinson-Detroiter aircraft, landed on July 4, 1930, at the same location, eventually forced to land because of technical issues.
