There is a big difference between evidence led research and science fiction. To all intents an purposes the RFI was an incident that, in Dec 1980, required a number of USAF personnel to go off base in the very early hours of the morning on at least two separate occasions. Of the personnel involved, a few witnessed something strange that has mystified them to this day. That is fact.
Many years later, in 1997, another person witnessed something strange at virtually the same location. That is also fact.
The area has a history of highly classified research and development into radars. It was also home to two major front line airbases, one of which housed nuclear weapons. Fact.
Following a directive from Winston Churchill in the days of WW2, there is a probability that somewhere near one or other of the bases but within the forest there is an underground facility used - or at least intended for use in WW2 - as a chem weapon storage area. The directive to build such facilities at RAF stations near wooded areas, all the way down the east coast from Scotland to Kent is fact but it is not known if any such facility actually existed at Rendlesham (or at any other of the RAF stations for that matter, after all the directive might have been a deception) - but given the role and location of the twin bases, the probability is high.
It is known that until Jul 73, OTH radar was being tested at Orfordness. Years before that Orfordness was used as a bomb testing range. At Leiston, just a few miles up the coast, is the nuclear power station Sizewell B. A few miles down the coast at RAF Bawdsey, there was more radar activity.
Therefore, the whole area has a long history of nuclear reactors, highly classified military activity, very highly classified research involving radar emissions and testing devices for atomic weapons.
it is known that Bentwaters has been de-commissioned but Woodbridge remains as a military base. At the time of the 1997 sighting a number of helicopters were seen over the forest and large numbers of what might have been standard British Army three ton trucks (Bedford M Type?) were observed entering the base - but these events might have been purely incidental and not in any way connected with the sighting in the field or the presence of persons in the field.
However, taking all these factors into account, the hgh strangeness sightings might well have been related to some kind of military experiment. Given there was (apparently) no restriction on access to the area, then perhaps whatever appeared in the field in 1997 was an unexpected outcome. It would be usual for such tests to be conducted at establishments such as AWRE, Skunk Works, Edwards AFB, Porton Down, Area 51 etc - but who is to know what goes on in the quieter parts of the English countryside? Even the farmer's field and the farmhouse could be owned by HMG.....and just to fantasise for a moment, even persons occupying the farmhouse and Folly House (at the eastern end of Woodbridge runway) might not have been quite what they seemed. Or, dropping back to the Dec 80 RFI, in an even more bizarre fantasy what if Halt and his men hadn't been sent into forest to find something but instead were actually tasked to seal it off, to make sure the area was secure before some other activity took take place. After all what better time to conduct a very highly classified experiment than in the period between Christmas and New Year when there was no flying, when many personnel were on leave and several of the locals might have been away. Plus, it has been said several times that whatever was going on was filmed.... could this filming have been part of some kind of monitoring or evaluation process? Were there any boffins amongst the personnel entering the forest? Was Hollesley Bay prison put on evac alert just in case whatever was going on went legs up (that suggests airborne involvement of some sort).
i still think the cousins accidentally dropped a nuke though............

You can fool all of the people some of the time and some of the people all of the time but you cannot fool all of the people all of the time (Winston Churchill)...causa latet, vis est notissima
