The test plane is N162W and it didn't look green in the last photo I saw in 2007 but then how many 1-11's would be at Hurn now?
It's actually N164W and it departed Hurn on the 29/3 for Keflavik and presumably back to The States.
The 1-11 currently at Hurn is the Omani one (553). The flag on the tail does have a bit of green on it but is more red!
