It was one of the ways Dutch soldiers tried to identify German parachutists in our unhappy 5 days stand against Germany in WWII, May 1940 - asking any unidentified stranger to pronounce 'Scheveningse schapen scheren' (shave sheep from Scheveningen). Or so. No way a German could pronounce this properly. The Dutch Schiphol = pronounced as Sgiphol, and any foreigner will make it Skiphol. Well possible that the FA used proper Dutch pronounciation in one announcement, and the English version in the second.
It is almost identical to the Scots pronunciation of 'ch' in words such as Loch. The tongue-twister I learned was: 'achtentachtig prachtige grachten'
