built in a once isolated area that should be brought to account for the sad unneccessary fatalities of experienced pilots whom had they not needed to avoid the obstacles and clipped the buildings on their low emergency approach may possibly have landed safely before the treshold.
Look up Broadwater Gardens on Google Earth - you will see that it is a couple of miles from the threshold of 21. You can't blame planners for allowing buildings at that distance. There are many urban airports with houses far closer to the threshold than that - Heathrow for example.
And while I am here can I add my vote for a merging of the two parallel threads on this incident?
