Anon you can take literally any image data and find "strings" in it. FFS. Try the experiment with an image randomly taken from the net. You are looking at binary data interpreted as characters.
I'll take a look.

Frankly I cannot tell what these guys are doing without a whole lot of digging. These 5 picked from a geographical area not for any other reason.
The 22 that you counted, how did you determine they were EMS /Medevac? Owner names? Photos? Hospital destinations?
