Appalling misinformed journalism.
"This means pilots are required to approach the airport at a much lower altitude than normal, in order to maximise the space they have."
I don't think I am going to change your mind. Did you watch any part of the Youtube video above showing a series of landings at JSI? Did you see any of them pass the threshold at 50 ft / touch down 300-500 meters down the runway? With the aiming point markers painted 150 m from the threshold where exactly are you aiming if you intend to
land it like at Heathrow?
You don't have to be as low as Wizzair, but it's certainly not "appaling misinformation". It's somewhat near the truth.
