I too saw this propaganda and had to scratch my head. No mention was made of how the single airframe could be in two or more places at once.
So...
I found this useful link for the DPA to follow:

P.S. Did you know...
"Propaganda is a specific type of message presentation directly aimed at influencing the opinions of people, rather than impartially providing information..... Strictly speaking, a message does not have to be untrue to qualify as propaganda, but it may omit so many pertinent truths that it becomes highly misleading."
