I think I posted a link to SKYLON a year ago... if they are willing to use Handwavium on the engine itself, they will quickly get something that can compete with the typical Fen engine.
If they want to keep the engine hardtech it will take longer, because they have to figure out what parts they can keep hardtech and what parts they have to wave. Maybe 2014-2016, as a part of the supply chain to Nouveau Paris?
