Jetways and aircraft doors

Over the weekend there were 2 incidents where aircraft doors and jetways connected in ways that they shouldn't (BTW no one was hurt in either incident). In the first incident, a Lufthansa A340-300 that was about to depart Denver for Munich had it's left front passenger door ripped off when the jetway lowered while door was still opened and the door was torn cleanly off. The flight was canceled and plane was taken out of service. See the following link: http://avherald.com/h?article=409f5eb1&opt=0
In the second incident, a Sterling flight that had just arrived at Malaga from Copenhagen was tipped almost onto it's back when the jetway hooked the front left door a caused the nose to rise. The plane settled with it's tail about a foot above the ground and it didn't appear to sustain any major damage although I'm sure the door is going to need some repair because it isn't designed to take the load of half the plane.

Rochester Airshow
There is going to be an airshow at Greater Rochester International Airport this weekend. Unfortunately I will not be able to attend it as I have a previous commitment at Oswego's Harborfest.
