Jet Engines and Propellers

Last Sunday, at about 5 in the late afternoon, I heard a very loud sound. I was not able to come out and see for myself but I knew that sound. It was a jet engine and a very loud one and very close overhead. On Monday, our MOD DAF who lived in Tanjung Nangka told me he saw jets. It was not until yesterday that I finally learnt that 2 United States jet fighters made an emergency landing in Brunei
