Luke – yesterday I was supposed to go to Sharm-el-Sheik at the bottom of the Sinai Peninsular but before departure at Gatwick we found hydraulic fluid escaping from one of the nosewheel steering jacks. The flight got changed to another aircraft as it took the entire rest of the day to fix the fault. The prospect of barrelling down a taxiway with no nosewheel steering was not tempting! Differential braking would still be available but is not a practicable solution.
