Thanks for the replies, but no I am not refering to Sungi Besi, i am very familiar with that field. The one I am refering to is approx. half way between KL city centre and KLIA. As you drive along the highway towards KLIA, on the left, fairly close to the road, is a structure that looks like a hangar and a landing stip. Next time I pass I will try and get a photo and post it here.
