Probably not of much interest but there was a previous incident of a pilotless aircraft in circuit at Wattisham. That one was a Hunter which did a wider circuit taking in Ipswich and I think the year was 1957 or 8. It eventually crashed ISTR on the outskirts of Ipswich. I was there at the time on Battle Flight with Meteor night fighters from West Malling and initially fast asleep until pulled out of bed to see the spectacle.
