It was a Let 410, DRC registered, that tried to taxi under the A310 wing.
These guys definitely enjoy a drink or two, and judging by the alcohol fumes they were giving off one morning in Bunia not so long ago, they like to get a nice early start.
I heard they tried to do a quick DYI repair job with the old trusty leatherman and some 100mph tape, but the Ugandan CAA were having none of it, and wisely suggested they should actually replace the effected tail fin before escaping back to the DRC.
