Having viewed a week's worth of videos, I can confirm that Paddington's first attempt at flying was indeed the moment he left the tray on the morning of Saturday 28th July at 10:39am
The same day, both his parents have visited the tray with food for him.
There was also a brief visit from a pigeon, a live one that is, for the first time in months.
Because there was so much footage to view, I have had to remove the video recorder to download the video files. It takes about an hour to download each day's video from each camera. Anyway, I will put it back in the next day or so to see if there is anything else going on.
If anybody does see Paddington around the tower, please leave a comment below. Thanks.
