Not sure if anyone posted this before.
The F15 Silent Eagle picture Q posted back on February 1st, 2019, post 2675,
Was apparently taken from the Wikipedia page 'Jet Engine'.
Circa 2014.
Wiki filename describes it as Air strikes in Syria.
Q didn't indicate that this was an original picture, nor was there any text in the post, other than the filename which Anons attempted to glean some meaning from.
Didn't know if the original sauce had been found,
Sorry if this is old news.
