Any flying school or light aircraft manufacturer are never far from bankruptcy. I would suspect that oil prices/credit crunch has had a knock-on effect on flight training.
Profit margins are small and regulations (CAA fees) and the cost of fuel make life increasingly expensive for UK based schools.
Equally many smaller airports are under threat from the planners and struggle to make ends meet.
I don't know about Aeros - I have heard good things about their operation but never flown with them.
I would put the question to them directly and if you have concerns simply pay as you go.
