American Airlines Grounded by iPads

[Sir Moody]

I'm not sure whether I would use cloud-reliant apps on an airplane, make them work offline and give them a spare in case the first one has a failure and most scenarios should be unproblematic.

The software in question is not cloud reliant - it is designed to work offline (according to Boeing's website) - it seems to work by downloading the maps while the plane is at the gate and connected and then running offline while the plane is in the air - id hazard a guess that the problem was in a failure to download the maps (since the article mentions the pilots having to return to the gate to fix the issue)
