The Zendmasts of Ruiselede were eight 287-metre (942-foot) high guyed radio masts at Ruiselede, Belgium, built in 1923 for carrying an aerial for VLF transmission (nominal frequency 16.2 kHz). On 30 December 1933, an Imperial Airways aircraft crashed into a mast and demolished it. Most of the masts were blown up by German troops in October 1940.
The masts were designed by the Belgian engineer Arthur Vierendeel.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
