Air travel during the time of the old world some strange looking airships here and perhaps zero gravity travel too or even teleportation who knows?? after all we are all made up of frequencies and they could have changed the surrounding frequencies to match that of bees and other clumsy looking flying insects which match the surrounding frequencies with their wings which makes them levitate and they manoeuvre or steer with wings and maybe the organs or bells of course destroyed or disabled could have peaked these frequencies who knows???
