On Saturday morning, October the 20th, 2012, just after 10am a recently sprayed chemtrail was visible in the sky to the west of Whangarei, one with undulations at regular intervals, that had a visible start point, as the photo below shows.
I looked on the computer to see what aircraft had just flown by. This plane was identified in real time using Flightradar24.com as ANZ99, an Air New Zealand plane. See a screen shot from Flightradar24.com below. No other planes were showing up on Flightradar24.com at that time in the Northland region, only this plane which was on its way to Tokyo. According to Flightaware.com it departed Auckland Airport at 09:21 NZDT.
Wrote David Quirey of Whangarei who kindly provided some excellent photos of the trail: “I’ve never seen a high altitude contrail like this. It was slowly blown in a North Easterly direction, and must have been visible for an hour. As you will well know, a jet engine produces a steady volume of high pressure exhaust gas, this “vapour” trail is clearly intermittent.”
Thank-you David, it is not a condensation trail and this is not the first time Air New Zealand planes have been identified spraying aerosol trails over Northland. Refer:
