The Kemble landing fees don't sound that drastic if the facilities have improved as much as is rumoured. The Bulldog rate sounds somewhat higher than average, as it's more than the going rate for Cap 10 dual in southern England (Sherburn does that for 50p in the old money, but that's in the frozen north), and Dogs can be rented for under £100 an hour solo if you know where to go, but perhaps the reality is that most places charge too little and, if instructors get slightly better paid and aviation businesses can make some profit, why not?
