Why can't an Ostrich Fly?

I was wondering why the ostrich can't fly? I heard its because they have small wings, but thier wings are almost as big as their torso. So why can't an ostrich fly?

    Ostriches can't fly because they have tiny (vestigial) wings. Ostriches are large birds, and weigh quite a bit - and therefore would need HUGE wings in order to fly. We're talking a wingspan of over 30 feet! There is a point where the weight of the body and the need for longer/bigger wings is not advantageous for a species. The ostrich is way beyond that metaphorical cut-off point.

    I hope this helps!

    The wings can't develop enough force to lift the ostrich.

    The ostrich belongs to a family of birds who gave up flight in favour of running to escape predators eons ago.His body is much to heavy now for flying

    Our government has tried to confuse you into thinking this. The real reason ostriches can't fly is because they are on the F.A.A.'s "No Fly List" as suspected terrorists.

    small wings and combine this with large body makes 'em unable to fly.

    their thrust to weight ratio is not sufficiant to support their weight
