From airmail to email, the bay area has a rich communications history.<p>From the Wikipedia page on Airmail:
"Starting in 1903 the introduction of the airplane generated immediate interest in using them for mail transport. An unofficial airmail flight was conducted by Fred Wiseman, who carried three letters between Petaluma and Santa Rosa, California, on February 17, 1911.[5]<p>The world's first official airmail flight came the next day, at a large exhibition in the United Provinces of Agra and Oudh, British India."<p><a href="https://en.m.wikipedia.org/wiki/Airmail" rel="nofollow">https://en.m.wikipedia.org/wiki/Airmail</a>
