ASN Aircraft accident 04-FEB-2015 Cessna 441 Conquest II N441TG
Wow - ur friend worked his way from Pizza Delivery driver to owner of 94 Dominoes Franchises.
Aircraft looks like either a landing attempt of hit the ground in slow level configuration - no emergency calls - new to the airplane - fuel issues? Fairly complex aircraft if he just transitioned into it.
Sorry for the loss of your friend.
