The fuel the Pig dumps is from its usable fuel load, that is the whole point of a jettison system, to reduce weight. Do you really think the GD designers thought, "hey lets put a slop fuel dump system on the 111 so it can look cool at air shows..." As for the safety concerns raised by Airtourer, yes there is a risk when an aircraft flys over a city, or flys at all for that matter and yes F111s have crashed. But so have 320's 74's 73's 340's etc and even airtourers, but most of those fly over the city every day. Can I suggest Airtourer. for your own safety, you stay indoors and wear a tin hat.
