Yes you're right, "touch and goes" were very common back in the day, especially in the military, even on the larger aircraft.
Even for fully trained crews there was usually a requirement to, for example, log x number of normal landings a month, x number of three engined landings (on a four engined type..obviously), x number of flapless landings...the list went on and a touch and go was a quick way of ticking them off.
In the days before really modern simulators the only way of doing them was on the real aircraft, maybe when you got back to base at the end of a longer flight (I gather that went down well with the "rear crew" )...
All probably a bit different now with high fidelity simulators but there's probably still the occasional requirement for some in the military to do them on the real machine.
