"flight demonstration".  Means that it will take off and land after few high alt cercles above your head. 
I was very excited   

  to see B26 "flight demonstration".  They start engines in front of you and taxi, (That was really great) then take off and fly traffic patern. 
Like I said before, If their is a airshow, then its going to be a blast.
