A corporate jet over-run is an unlikely problem. All have or should have accelerate-stop/go capability.
If really concerned, ban all the singles and light twins that CAN'T clear the houses, tramlines or freeway after an EFATO. A concrete crash barrier won't do these things much good if an engine quits just as they clear it. Send the bugsmashers somewhere suitable for their own and everyone elses' safety.
Don't ban the airport - we have enough of these assets under threat already.
And if you think I am anti-bugsmasher, I am not. I fly a very light single sometimes, but no way it's ever going near Essendon or any similar airport where the options for a forced landing are so limited.
