I believe TNT is pretty stable. In his memoir "Target Ploesti", Leroy Newby tells of an incident where B24s dropped their bombs if they were running out of runway on takeoff - something they would not have got away with if the bombs contained RDX rather than TNT. It was a hot day, the planes were heavily loaded, and the first to go ran off the runway and burst into flames. Newby's was next, and his pilot refused to go; this was the compromise they worked out.
