I wouldn't buy TMPS either solely because Johan is the owner.
I'd buy it because it's a relative cheap stock that is producing revenues, has established relationships with the US military, and has a relatively small float because most of the shares are held by a man who will never be forced to sell his stake prematurely because he needs the cash.
I'd buy it because right now, it's trading well below the .52/share that they acquired the planes for -- and you have to imagine that whomever sold the planes did so with the presumption that one day those shares would be worth more than .52.
I'd buy it because at these prices, it's very oversold from its recent highs.
