Yes, the statement from the US Army referred to the crew having to make a forced landing without gear.
However here is a report from 2002 regarding a Canadian Citation II “The crew did not complete the before-landing checks, ignored aural warnings, and did not lower the landing gear, which resulted in a gear-up landing.”
Transport Canada C-GYCJ Citation II Nov 12 2002 Sandspit Airport - Vancouver Island BC.
(No injuries to the four on board)
The crew only found out they forgot to lower the gear, when they went back to retrieve their personals from the plane, and saw the gear selector was in the up position. They thought the nose gear had collapsed on landing causing the accident!!!
