Well, to be fair, Delta haven't got a plug to pull. It's AFT who have fallen out with Delta and are terminating their sub-contract, Delta have never been approved to provide JAA training in their own right. Presumably, the 'JAA' PPL will be the same ersatz version that UKFT provide - actually a FAA PPL with a JAA 'conversion' tacked on the end.
So, WMU have gone, Delta are going, IFTA is all but finished - is the writing on the wall for overseas JAA training? The CAA's line seems to be that EASA will take responsibility for the overseas training organisations away from the UK and allocate individual organisations to different countries. Given the antipathy in most EU countries to modular training in the US, it could be that these three FTOs are jumping before they are pushed.
