Lets See Your Aviation Stamps

1977, Spain, 50th anniversary of IBERIA Líneas Aéreas de España, "RohrbachR-VIII Roland and DC10-30," 12 pta., EDIFIL nr. 2448

Iberia's first flight was executed by the RohrbachR-VIII Roland M-CBBB on 14 December 1927. The first flight would fly from Carabanchel (presently Cuatro Vientos) to Barcelona with King Alfonso XIII. However, to have the king present to see the landing, the first flight was two hours before that first official flight from Barcelona to Carabanchel.

I apologize in advance, this is the only way I own the stamps:

It is unique in the world that the cargo hold of the jumbo jet is accessible and the left wing can be climbed at a height of 20 meters (65.62 ft).
