Cameras in the cargo hold - good . Thermal imagers in the cargo hold - better. Seeing a 'hot spot' before it bursts into flames might buy some valuable time. Cameras enabling flight deck to have a look see at engine pods, landing gear, etc. - great.
Ac makers griping about cost and weight - plain bs. Every rinky-dink cellphone comes with a hi-res camera the size of a pinhead. Besides, with them ac makers experimenting with electrically powered wheels in order to do away with the towbars,tugs and taxi fuel, crews will need some good cams in lieu of a rearview mirror
