There is a talk at the Wheatsheaf hall in Vauxhall by Mark Hempsell on Wed 22nd January. If you know about this already then the venue has changed to let more people attend.
You'll need to buy tickets. Mark Hempsell consults for Reaction Engines and was their Future Programmes Director until quite recently.
