The 6th annual Over the Air will be held on Friday the 27th & Saturday the 28th of September at Bletchley Park.

For two days up to 600 mobile developers & designers will be based at Station X, hacking in the shadows of the WWII Enigma & Lorenz code-breakers, and hanging out at the home of Colossus the world's first programmable computer.

Over the Air is a unique tech-agnostic event for and by the developer community, featuring technical workshops where attendees can roll up their sleeves and tinker with new platforms, operating systems, APIs & SDKs; and tutorial sessions that feature real business cases & new insights.

Our first year at Bletchley Park we explored the themes of security and encryption, last year we learned more about Alan Turing's legacy and explored Citizen Science.

And this year? ....more greatness!

On Friday evening there will be a series of inspirational Ignite Bletchley Park talks, which we also open up to the community for proposals. Attendees will be invited to stay overnight so that they can work on ideas, apps and hacks on the fly – to be entered into the various Hackday competition categories and demo’ed on the second day.

It’s a great vibe of bean bags, gadgets, knowledge sharing, hacking & lots of good geekery.

It's free to attend, other than a small £5 donation to charity (yet to be deterimined), and a breeze to reach from London Euston Station.
