My only 2nd hand contribution to the original question ... when Tengah’s 20 Sqn Hunter FGA9s went to Seletar for Major Servicing, they were stripped of everything. Tanks, Pylons, Gun pod, Sabrinas etc. There was a roster as to who would fly it there, Utterly clean, and stripped to the bone, it apparently generated 20 minutes of intensive fun before a fuel priority recovery to Seletar.
