Passengers disembarking Iberia Airlines jet aircraft via mobile stairs on airport tarmac in 1970s

Passengers descend mobile aircraft stairs from an Iberia Airlines jet on a sunny airport tarmac, likely from the 1970s based on clothing and aircraft livery. This photograph captures typical commercial aviation operations of the era when Sir Freddie Laker was revolutionizing low-cost air travel. The scene shows the formal boarding procedures common before modern jet bridges became standard.
