I mentioned the Red Arrow earlier today in my post Through the Blue Window. I saw the jet during Chrisof's wonderful looped images shown throughout the TV21 con. Reader John Swan, who was there too, has kindly informed me that the red jet is from the Thunderbirds TV episode Edge of Impact. Courtesy of You Tube you can see it at throughout the first 8 minutes of the show. In particular you can see it turning , around 17 seconds in, on the You Tube clip above. I was keen to see more angles of the jet and establish any further similarity with SWORD Probe Force 3, which I'd begun thinking after seeing Chrisof's fab interpretation below.

Can anyone make a few screengrabs of the jet in Edge of Impact to show it at various angles so we can compare it more closely to PF3?
