There are some instructors that make you want to make a veeeery big curve and walk past them not closer than 3nm if you meet them one fine day...I think they deserted the army

I would be carefull with Hub'Air, certainly when you are about to spend a Mercedes with them - not too much info around although they claim to train for major companies but when you ask the company involved you get an answer saying - never heard of that...at least bizar...
