I think the read backs came after lots of crashes into control towers and other stuff...
Although, as a HAM radio operator serving my local fire department in disaster training, I was chided a bit by a FF (who later became chief) who was in the Special Forces at the tip of several spears. He kept reminding me and the other HAM operators that the longer you talk on the radio, the easier it is for the enemy to figure out your position. So in wartime (or military training), the radio calls and responses tend to be very short.I think the read backs came after lots of crashes into control towers and other stuff...
Yea, you don't want to be drawling on and on with those landing clearances like they do at LAX or JFK
As one of the comments says, I reckon the war was over before they got through that pre-flight checklist...
