Could an assault on the White House actually happen in real life just like in both White House Down and Olympus Has Fallen?

Answer 1

It is certainly possible for those kinds of assaults to take place (they do not violate the laws of physics), but it is highly improbable that they would be successful. There are numerous safety protocols that protect the White House and the area in Central Washington D.C. For example, the plane that launches the initial strike in "Olympus Has Fallen" is operating in a no-flight zone for any civilian aircraft. After sending a warning, a missile would have already been on its way to intercept and local troops would be mobilized on the ground. Conversely, the security that each person needs to pass through would likely prevent the kind of bombing that occurred in "White House Down". There is a reason that no terrorist group has yet tried to attack the White House; it is one of the most secure locations on Earth.
