Although Glen was a bit of scalliwag, he was an excellent instructor and pilot.
To the best of my knowledge, Mel has carried on that tradition and although there may have been some up's and downs in the period immediately following Glen's untimely demise, I think things are stable now and it's as good as any organisation within the area.
It wouldn't hurt to take a trial lesson with the Humber Flying Club, John (the owner and CFI) is "straight talking" to say the least, but he has an excellent record in getting students through all levels of licences.
There is/was another flying club at EGNJ, but I've no knowledge of them.
