The delay in the air is minor. Radio travels very fast through the air. Almost at the speed of light. It's the electronics that are causing the delays. The less electronics touching your signal the better. The up and down is very fast. But then you have all the converts and the land line links to factor in. Microwave also has delays such as the Motorola equipment which is only half duplex. This will also incress the time. Max is right, check into some ground based systems.Huh? 44,000mi (up and down) @ 186,000mi/sec = 0.24sec. Not a minor latency for voice comms.
Before undersea fibre made undersea cables cheap, satellite was far cheaper than undersea copper. In those days intercontinental calls were usually satellite one way and undersea cable the other. When satellite was used both was conversation suffered badly. If you made a call from Europe to American, and it was satellite both ways because the cable was all used up you really know about it, and often abandoned the call. 2 x 0.24s is getting beyond the limit of what is reasonable.
