Field Trip

My Intro to Aeronautical Engineering class went on a field trip to WMU's School of Aviation today. We got to see the Cirrus SR20s that the Aviation majors get to fly. I can't express to you how jealous I am. I want one. Badly. All I've got to do is save up $450,000 and I can buy one.

Is is Cirruses or Cirri?
