Many thanks sablatnic. The tow aircraft were not 110s in the film clip, as they were single fin. Only saw them in rear on and distant view, hence the inability to positively identify, but definitely not 110s. Thanks once again.
Edited to add the film clip is here, 21 minute mark

The tow aircraft don't show up well, but to these tired old eyes on the wide screen telly I was sure they were single fin. Stand to be corrected.
