I didn't find that amusing. This cruise will go to the wreck site to perform memorial services, broadcast images to schools on three continents, and to honor those who died in the waters.
Just an FYI, there are many memorials to those who perished at the WTC site, and I myself have been there to reflect and give homage to those who perished.
On this trip are passengers from the UK, New Zealand, Canada, Switzerland, Germany, France, Ireland, and from the states of Alaska, Connecticut, NJ, MD, NC, SC, FL, IL, CA, MA, Missouri, and LA. Several other states are represented as well who are going for many reasons.
