I took the liberty of bolding the key word.
There's some games going on.
Yes, there are. Mostly by the tanker owners. There are some reports that they're skimping on maintenance.
"skimping" on maintenance on a 50 year old airplane that's only flown a few hundred hours a year is a relative term.
I'm an ex AirForce mechanic, commercial pilot, and A&P. I could ground any aircraft, anywhere, if you just give me time to look hard enough. I've seen military aircraft "grounded" that had nothing wrong with them. I've seen the same type airplane signed off as flyable with 6 inch cracks in the spar (I'm not responsible for either case).
I frankly don't buy it that "all" the tanker fleet is suddenly "unsafe". If they grounded some of them, AFTER doing specific inspections, fine. But not all of them, from every operator, no matter what type.
Something fishy is going on with the politics of this.
