-AMERICAN 1, number 1, clear for the option RW1
-DELTA 2, number 2, traffic to follow is on left downwind
-DELTA 2, maintain lowest practical speed
-Delta 2, number 2, clear to land
What is the message to the ATC if American 1 pilot don’t see a safety landing before the Delta 2 landing and American pilot wants to extend downwind and land after Delta 2?
