I know that ATC is not as perfect as we would like it to be but still it does some strange things but this is the strangest I've ever had. First I had the AI slider turned up to 90% and was using Just Flight's Traffic for FSX. I was cleared to depart from runway 19 at Reagan International. Only problem was that ATC also cleared a 737 to depart on runway 1 and cleared another plane to land on runway 1.These are the same runways!!!!! Why did this happen and does anybody know how to fix this?
