Can someone find out more about the tallest structures of Japan?
* Iwo Jima LORAN-C transmitter ( http://en.wikipedia.org/wiki/Iwo_Jim...-C_transmitter
), whose 411.5 metre mast collapsed in 1965 and destroyed thereby also the transmitter building. Was it rebuilt?
* Former OMEGA Transmitter Shushi-Wan ( http://en.wikipedia.org/wiki/OMEGA_T...ter_Shushi-Wan
), 389 metres
* Marcus Island LORAN-C transmitter ( http://en.wikipedia.org/wiki/Marcus_...-C_transmitter
Please update the articles over these structures in Wikipedia.
