{| |} The Clément-Bayard No.2 was a French military airship of 1910, developed by automobile manufacturer Clément-Bayard. Unlike their previous design, this aircraft was designed and built entirely by the firm itself. On 7 September 1910, the airship was used to make the first aerial wireless communications, sending and receiving messages to the Eiffel Tower with a 65 kg (143 lb) transmitter carried aboard.
