I really don't get this question. I have been on thousands of night flights, and I have been through hundreds of airports, and I could always hear the engines, day or night. And, because your normal daylight traffic sounds are less, sound carries better at night, so you can hear the sounds of the aircraft farther at night, even farther than you can hear in the daytime. Higher frequencies definitely travel better at night, too. Unless ..., you were asleep, and didn't hear them? I am stumped.
One possibility: There are fewer flights between midnight and 6 am: major airline traffic at most airports starts at about 7 o'clock in the morning. So, perhaps you don't hear so much aircraft sound, because they schedule fewer flights at night?
