This is true, I know practically nothing about the flying side, apart from when I was last there one of my ex-students was doing a CPL course and she was having a positive experience, although she hadn't finished. I'm assuming Matt has searched PPRuNe.
B2N2 illustrates some of the ghastly behaviour from US flight schools in the past, hence their generally poor reputation. He left out visa shenanigans and shockingly poor maintenance which also feature(d). It is certainly true that there are ATOs in the US that I would not do business with under any circumstances because of the damage to reputation that would inevitably follow. NAC is not one of those, but you must make your own mind up. If you can't/don't want to contact NAC and ask these questions then suggest you ask Andrewsfield Aviation in Essex, as its their approval potentially at risk if there are any dodgy doings. If you have any doubt, look elsewhere, there are plenty of options in Europe.
