There is one privately owned and flying in the USA.....from what I understand when he purchased it they never expected it to flown, just a museum piece. The guy happens to have flown them in the USN and his home town had a large number of Harrier engineers on hand so hey presto! Air Show Material!
Somehow I think it was not likely to happen again
just like the F111
here is some footage from my trip to Oshkosh this year
towards the end is the Harrier display!
