Pan Am had had a resurgence towards the end of the 1970s however the purchase of National Airlines and the effects of deregulation sent the airline into a nosedive it was never able to recover from. Still amongst the gloom some positive changes were made and one of them was an attempt to re-equip the fleet with more suitable products in the form of Airbuses. The airline planned to standardise its fleet around 747s, A310s and A320s however the latter would never get to wear the famous globe on its tail.
