Could you please point out where "restrictions" are mentioned? I couldn't find them.
I refer to the veiled inferences in comments such as:
"We will make sure that this petition is delivered to the Prime Minister and we will not remain silent on this issue until he takes positive action to close this legal loophole and bringing gliding under the control of the CAA, just like airlines are."
"some gliding bod spiralling up in the cloud in a completely indiscriminate fashion"
There are more. If my point is missed, forget it. This is only a debating forum, after all.
