About 25 years ago I was hauling cargo in a beat-up C210 at dusk near PFN, FL, and overheard the following:
ATC: “Comair 1234, Nat’l Wx Service just advised us they have recently released a balloon in your area and they say “it should be approx your altitude, and it’s pretty large.”
Pause of a few seconds…
Comair: “How large?!”
Pause of several more seconds….
ATC: “He says about the size of a house.”
Pause of a few seconds:
Comair: “Would that be my house or your house?”
