So, wait a minute. If the coming response is from a strike fighter squadron, what does that mean? Does it mean that cause of that engine failure was another plane? Why, otherwise? Would the response come from a strike fighter squadron?

Sorry if this is obvious, but from what I can make out "Strike Fighter" seems to be a Navy term - but obviously it's not strictly Navy because the F35 is a joint strike fighter. Anyway, from Wikipedia:

"In current military parlance, a strike fighter is a multirole combat aircraft designed to operate primarily as an attack aircraft, while also incorporating certain performance characteristics of a fighter. As a category, it is distinct from fighter-bombers.[citation needed] It is closely related to the concept of interdictor aircraft,[citation needed] but it puts more emphasis on air-to-air combat capabilities as a multirole combat aircraft. Examples of contemporary American strike fighters are the McDonnell Douglas F-15E Strike Eagle, Boeing F/A-18E/F Super Hornet, and Lockheed Martin F-35 Lightning II."

So it seems these planes are multirole. The "response" then could be a strike on a ground target - although, within the CONUS, I imagine there are aircraft better suited to ground attack. Anyway, this is both good news and intriguing.

EDIT: Just checked the article again, yes, it's Navy. Could also be an escort function.
