AC, I totally sympathize with you, and your childrens lack of sleep but I wouldn't be of much help as the noise doesn't affect us as much here (1/4 mi. as the crow fly's), and I don't mind the outside seating situation.
I crindge everytime a plane takes off from LA..
Laconia airport,but it was there when I bought my house.Not that I'm comparing the occasional take-off and landing with 7 hours of constant boom boom boom.
I really hope you gain some ground in your quest and will be watching for the outcome..again I wish you the best..Tim
