There were a number of 60/64 Javelins lost at Tengah in 65/66, at least four that I recall.
I was back in Singapore 1974/76 [Flt LT RNZAF]in ANZUK, and briefly lived in an ex-RAF MQ at 12 Hyde Park Gate at Seletar, and piled three deep in that corner of the airfield nearest the Officer's Mess were all 60 and 64 Javelins!
