I'm sure you realize that the Patriot system has been upgraded some in the last 24 years.

However, I think one of the brilliant things about Iron Dome is the fact that it doesn't try to shoot everything down. If a missile is determined to not threaten anything, it is allowed to crash on its own.

That may not be as big an optimization against opponents with good aim, but the people who fire rockets at Israel are often using old equipment that they can't aim well.
