WHOOPs sorry - I thought it said 2017 for some reason - I too thought you had to go landside - that's what I did last time but then wondered if I had just missed it somehow!
In that case I really think this would be a very stressful connection to make and many points where it could go wrong - I would only book it if I were happy to be on the next flight (though the shuttles from Manchester can be very busy at times so I'd even be worried about that....)
