ExaScot gets bent out of shape about gliders.....
He grumbles that they are "a bunch of amateurs who don't show up on radar, are difficult to see, and have very little control over their flight path!"
All quite true. Item one; can you imagine the enroute controller who has to deal with a gaggle of fifteen or twenty returns on his radar screen all going around in circles at different levels of the same thermal?
Yes, difficult to see, especially if you have so much equipment stacked up in front of your face there is not a lot of window left for you to see out of your fast jet transport, and so are dependent on the poor overworked enroute controller to keep your path clear of intruders....
And as for very little control over their flight path? Let me assure the grumpy expat Scot ex meatbomber, that the flight path of the glider will follow the energy as is necessary to gain height and to complete the flight as planned.
If he is actually flying now in Greece and Botswana, I very much doubt if he is dodging a lot of glider traffic in these exotic locations.
