One of the reasond I brought this up is because the notion of needing a lot of space is also changing. Up until this summer, anything I flew needed a take off run, and a considerable amount of room for final and landing. Not any more. The planes are getting more radical, with longer chords, shorter spans, higher lift, lighter, and more alternate materials and building techniques than I can keep up with. I'm already flying .46 powered glow planes that fly out of my hands, and can be landed harrier style with no forward speed...and flying within the confines of the ball field (we've done it) is no problem. The only thing stopping us from making a habit of it is noise. The aircraft designs and flying style also opens up just about any place that has enough room to park a car and has a little overfly area. Again, noise being the only real problem.
