I saw the same 707 Nuno. I was working from home and saw a 707 on finals to YTZ
over the Toronto Inner Harbour. Wheels and flaps all down. It pulled up short of landing and flew south over Lake Ontario. A few weeks later, a CAF CC
-150 (CAF A310) was also on finals at YTZ
and then pulled up. Neither COULD land of course. 2 interesting sightings.
I dumped at the gybe mark in strong winds when I looked up at a Porter Q400 on finals. Can't stop spotting.
