Like puzzles? Get ready for the Day in the Cloud Challenge on June 24th

Flying 500 miles per hour at a cruising altitude of 35,000 feet, it always seemed odd that I could use approved electronic devices, but I couldn't get online to chat or send an email. Luckily, the Wright brothers have been catching up with the cloud, and airlines like Virgin America have rolled out in-flight WiFi across their fleet.

To celebrate, we've teamed up with Virgin America to provide complimentary WiFi on all flights on June 24th, and we're co-hosting a timed online scavenger hunt called the Day in the Cloud Challenge. Whether you're going to be in the air or on the ground on that day, you're invited to participate in the challenge and can sign up at www.dayinthecloud.com.

If you use Gmail, there's a good chance you already have a leg up because some of the questions will involve your knowledge of Gmail (plus, you'll need a Google Account to play). To give you a little practice, we've just revealed some practice questions.
