I heard some retired commuter pilot on the news last weekend suggesting
that the only way to prevent this in the future is to put traffic lights
(stop / go) on the end of every runway. I absolutely got the impression
that he was there to convince the public that it is almost impossible
for the pilots to get it right and the lack of the traffic signal was
the whole cause of the problem. Sort of the typical "not my fault" attitude.

If he thinks that is the only way, he is clueless.
