In the last five years I took 500 flights (all on economy class except for two), and I also took about 100 train rides. 
For &quot;short&quot; trips (&amp;#60;600-700 km or 400-500 miles) train might be slightly slower, but there&apos;s essentially no dead time and it&apos;s cheaper (no rush to the airport, no stupid security checks at the airport, no weather affecting the trip, no big delays, no taxi trip from arriving airport to city center). As a consequence, we should &quot;aggregate&quot; airports and use them only for long range travel, and revert to rail or road for shorter trips. By doing this, we would maximize the frequency and availability of flights from these mega-airports.
Then, by simply providing more leg space, power, and possibly internet connection, we could make flights &quot;suck less&quot;.
This is doable now. Any other technology would take decades to develop.
And again, most people don&apos;t need to travel NY to Hong Kong in 3 hours. Most people need to travel cheaply, and possibly in a green way.</text><parent_chain></parent_chain></comment><story><title>Elon Musk - The Future of Energy and Transport [video]</title><url>http://www.oxfordmartin.ox.ac.uk/videos/view/211</url></story>
