I’m very sorry to tell you all that my good friend, sanitation expert, podcast collaborator, bon viveur and fellow raconteur David Andres passed away suddenly from natural causes at his home in Houston on 7th January.  He was 57 years old. This episode is an abridged version of Dave's account of the sanitation response at Ground Zero following the terrorist attacks on the World Trade Centre on 9-11. It was originally published in 2021 on the 20th anniversary of those attacks. I’d like to send my condolences and thoughts to Dave’s children, Jackson, Madison and Hayley, his wider family and his many many friends and colleagues around the world.   God Bless you Dave, I’ll miss you man.
