I am absolutely in agreement that the present situation is dire, how it was arrived at and how it was handled is deplorable; I look forward to the resumption of ATC Gliding.
However
I supposed when you've never been a QFI it doesn't occur to you how terrifying/impossible a circuit with 8-10 gliders on ab-initio training would be.
It is neither terrifying nor impossible - I started my gliding on Cadet Mk3s a long time ago, and have been gliding ever since in the RAFGSA and BGA, including several years as a CFI.
Where I fly it is highly likely on any good day for there to be 8 + gliders in circuit, including ab-initio training. It teaches a good lookout from the start.
(How many gliders can a concentrated site launch 'simultaneously'? )
Nothing above detracts from a wish to see ATC Gliding resume on as large a scale, and at many sites as possible, as soon as possible.
