This comes from a good friend of mine who is an air traffic controller at Elkhart, Indiana.
Overheard on O'Hare Tower
Blimp: "Airship one is clear of your airspace requesting a frequency change"
ORD Tower: "Frequency change approved. I am not sure what a solution is, but it was a pain having you guys in and out of here."
Blimp: "Well we would much rather had gone to Meigs, but you all bulldozed it. Keep complaining and next time we will file IFR and make an ILS approach."
