On Monday 16 March, VH-JFE and VH-QQY operated morning and evening flights into Emerald from and back to Brisbane as UTY4060/4061 and from and back to the Sunshine Coast as UTY4068/4069 respectively.
Early on Tuesday 17 March, VH-QQY was then operating as UTY4062 from the Sunshine Coast to Emerald but failed to land in Emerald due to a technical issue. Flight radar websites show that VH-QQY circled Emerald Airport for a short while before returning to Brisbane. A little later, fellow F-70 VH-JFB then flew into Emerald from Brisbane as UTY4062, later departing to the Sunshine Coast as UTY4063.
Finally, late on Thursday 19 March, VH-QQY flew to Emerald once again, from and back to Brisbane, this time as UTY4066/4067.
It's also worth noting that on Wednesday 18 March, the weekly UTY1070/1071 FIFO flight that Alliance also operates into Emerald for one the Middlemount mines was operated by VH-JFE.
