Broadband at 30,000 feet: on board with Gogo's 2Ku

Gogo claims to be able to supply 70Mbps of capacity per plane, eventually rising to 100Mbps, although in practice the service is throttled to give everyone a bite, and the maximum speed a user will see is 25Mbps.

On the test-flight, a team of aviation and technology journalists did their level best to make the system fall over by streaming, Tweeting, emailing, and connecting to their company VPNs.

They did not succeed.
