... of the coverage at the time was the news reports that traffic chaos built up very quickly in the area with loads of ghouls converging on the scene.
I was not living in the UK when this happened (aged 14) and only know about it through PPRuNe references over the years.
From the report, linked in this thread:
The field was sufficiently inaccessible to prevent all but the most persistent sightseers from reaching it. The police were successful in controlling spectators, and contemporary reports that members of the public had impeded rescue services by their presence near the scene are not borne out by the facts.
So there might have been a number of people trying to see but they did not get in the way.
