All I know is that I looked at the fuel gauges instantly when the man on the other end of the radio said..............ML tower being evacuated expect holding & come back next week! Or words to that effect! Then it was holding, vectors slow down speed up cancel speeds the usual chaos etc & finally a Ldg around 20 mins or so latter so not to bad. Smoke haze was fairly thick, saw HIAL at around 2.5 to run to R16 threshold.
The new Twr toaster must have teething problems as has been mentioned
