I will try not to stray too far off topic here, but the BA incident illustrates that aeroplanes do sometimes come down in places not neccessarily intended for them to be.
Your point about various detritus in the undershoot is true ( all of those things are installed at airports as a matter of course ) but , as seen in the photo, the stricken aeroplane needed, and had available a CLEAR level area upon which to flop, and the injuries incurred were due to a high rate of descent, rather than hitting anything.
At Duxford, these incidents have happened before, it is quite possible they will happen again. DC-3 ‘s fly in with 30 odd pax, what if one performed a leap like the Mustang, dropped a wing, and cart-wheeled ? How will that affect ongoing operations ?
Why plane the surface, why not fill in with soil, roll, and grass over ? It is not about moving mountains, just flattening an 18 inch lip.
Which part of THIS to you take issue with ? ( ICAO Annex 14 )
”Runway End Safety Areas (RESA) are a formal means to limit the consequences when aeroplanes overrun the end of a runway during a landing or a rejected take off, or undershoot the intended landing runway.
They are constructed to provide a cleared and graded area which is, as far as practicable, clear of all but frangible objects. It should have a surface which will enhance the deceleration of aircraft in the overrun case but should not be such as to hinder the movement of rescue and fire fighting vehicles or any other aspect of emergency response activity.
Minor aircraft runway overruns and undershoots are a relatively frequent occurrence. Most data sources point to significant occurrences on average once a week worldwide and suggest that runway excursions overall are the fourth largest cause of airline fatalities. It has been stated by the FAA Airport Design Division that approximately 90% of runway undershoot or overruns are contained within 300 metres of the runway end. The contribution which RESAs can make to a reduction in the consequences of such over-runs has frequently been demonstrated as has the avoidable hazardous outcomes where they have not been present. ”
