People die everywhere. It is not the fault of the author of this parody. He/She did so due to the actual design of the memorial plans. If you must find fault find it with the original design. Think about it. : )
Absolutely! This is not poking fun at the deaths of the heroes of flt 93, it is poking fun at the idiots who designed the last memorial.
One of the most important things which allows the American people to rise above and continue on following a disaster is our ability to laugh and to find humor in the grimmest of events. It is the nature of Americans to never give in to maudlin feelings of grief. Americans never wallow in grief, we grieve and get over it so that we can move on to kicking butt.
