Interesting. Walking through Bury St. Edmunds on Monday, approx 10.30, there were two Pumas, wheels down, one of which circled very low and appeared to be landing at West Suffolk Hospital. It disappeared behind trees in that vicinity at about 200 feet. The other Puma circled overhead, wheels down, at approx 1,000' I remarked about it to friends at the time that it was rather strange, although Emergency helos are fairly common at the Hospital.
