There is at least one T-1A/T2V-1 Seastar that is either in flyable condition or near flyable condition.
http://www.acemaker33.com/airshow-info.htmlThe thread referenced by Zane in the above post concerned this aircraft based in Arizona.
Apparently there was hope that it would be available to fly at some CoNA air shows/events this year but to the best of my knowledge it has not.
I remember someone saying a while back that the Seastar was in need of a new windscreen or canopy or something along those lines.
I would love to see it in the air.
