Hi Brian,
The article does not state specifically.
"Memorial area near to the site of the accident to remember the lives lost and pay respect to the families whose lives were effected by the tragedy"
My interpretation is both.
Link here but No 69 with a very nice pick of HM on front cover not available at the moment.
About Town | Huntingdon Town Council
My own view for what it is worth. - Any memorial up there will soon be vandalised.
