1) According to the AFB regs for the airshow, aircraft had to arrive by Wednesday May 16 @ 6:00PM (assigned arrival slot was probably earlier), and could not depart until Monday May 21. With scheduling and positioning, that's almost 5 days of this aircraft being out of revenue service. I am assuming that the pilots and ground staff are donating their time. Based on the Delta culture, I can understand thier willingness to promote the cause, however the financial impact must be significant ?
2) Is it common for regular commercial aircraft to appear at military airshows?
