You feel for SACL? They would make enough to pay for this RESA project after 15 minutes in the motorcycle lane in the T1 carpark. If there were any other way on Allah's green earth that they could avoid donating money and time to this do you think they would? Do you think they'd go ahead with works if they didn't have to out of concern for passenger safety? Hardly.
A bit of concrete and dirt will do NOTHING more to save anyone if a jumbo careers off the end of 25. What it will do is keep the regulators at bay, which is all SACL are interested in.
