The charter craft for the Middle Tennessee State University girls basketball team. They were flying out to San Jose, California for the Women's NCAA Basketball Tournament's first round. That is a British registration and "Excel Airways" titles on the engines.
Odd thing abot this particular aircraft is that it is a rarity to see it here in the states. Google search the registration on the net and you will see it spends the majority of it's time (99%) in Europe. So that made getting this aircraft even that mroe special!
