Clare’s posted a report and some pictures from ‘CuzzieBro’ that showing ‘trails’ over Adelaide.
Surprisingly, the report contains enough actual facts to make some sort of analysis as to what was going on. Using flightradar24, CuzzieBro established that the plane in question was Thia [sic] Airways THA461, and it was at a height of 37000ft when his pictures were taken. Not surprisingly, neither CuzzieBro nor Clare bothered to take the extra step of trying to figure out if the atmospheric conditions at that time were conducive to contrails.
At a height of 370000ft (11277m), for Adelaide Aiport on the 31st of October:
- Temperature: -54C
- Pressure: 223hPa
- RelH%: 42%
