I have found something which may interest everyone or else everyone knows it. If you get the sea plane (not the helicopter it doesnt go high enough) as you already know if you dive down nose first from a high point and with great speed go back up you will go much higher than a helicopter. Well do this beside high buildings,to my knowledge ther are only 3 buildings this can be don to,2 on the first island beside the beach near North Point Mall and the other near the Cherry Poppers Ice Cream(ALL 3 ARE HIGH BUILDINGS). If you try and land on top you will find they are hollow and have no roof and you can fall down inside them, then jump down onto the ground on the inside and you will see the city above you, upsidedown. No roof big mistake.You will keep falling until you land on the ground outside the building
