MrBernoulli, it's a reference to the fact that the Phoenix drone is well-known for its ability to do its own thing, usually ending in a terminal dive. Hence an impromptu entrenching tool.... It was also nicknamed the 'F**koff', I understand, due to its reluctance to follow the drone operator's instructions...
New pongo drone flies. Oh good. Yup, not exactly in the same league of interest as Concorde's maiden flight 40+ years ago.....
