Active duty AF retired theirs in 2004, AFRES retired theirs in 2006. C-17's went operational in 1995 and eventually replaced the C-141B.
The Starlifter was a great aircraft, I have just over 400 hours in them as a Flight Nurse, I served from 1987-1995. Our squadron was involved in the medivac configuration planning for the C-17 in the couple of years after Desert Storm. I never got to fly in the C-17 though.
C-130's will be like the B-52, probably around beyond our own lifespan. They have landed on aircraft carriers. The video is as fake as Astroturf, probably done on someone's flight simulator. I think the C-17's weight would prevent that possibility even if the other parameters could be met. I didn't even watch all of the video, I could tell from the approach it wasn't real, and neither the Navy or USAF is going to put F-35's at risk, as there were a bunch of them parked on the deck, preventing any possibility of a bolter for the Globemaster.
The 141 is not a bad ride but the C-5 is the best. Never been in a C-17 and never want to ride in a Herc again!
