Hi Gary,
I can’t confirm the exact times etc, but I can confirm it’s not the JT 707 as its actually the Qantas Founders Outback Museum’s 707, now VH-XBA but formerly HZ-123 that has been in storage at Southend for a few years.
There’s some nice photographs of it in its full period Qantas colours over on Airliners… plus more detailed updates on the UKAR forums.
Regards 🙂
