I was wrong there was one at Newark one at Logan and one at Boston so I guess it wouldn't seem as obvious but there still didn't look to be far between each airport I still think if airports are close together there should be a 15 minutes gap between planes if same airlines the plane that took off late what was reason cos if it hadn't been late the sequence maybe wouldn't have happened was it passenger related as if case id say above. 10 minutes late were not waiting or was there a passenger missing if so were they one of hijackers
