G'day from sunny northern Tasmania.
In last few weeks I have twice spotted 4 engine jets (presumably 747's) heading south over Launceston LTN. They were both at what appeared to be a cruising altitude, & could clearly see the 4 con-trails. The second one was definitely a Qantas aircraft as the paint scheme was clear (Red tail/white body).
I know there are no airfields in Tasmania that can handle a 747 so thought they may have been heading south to pick up an easterly or westerly jetstream en-route to either South Africa or South America after departing Melbourne. Can anyone shed any light?
