Just a few months after this unique video was taken, the Boeing 747-100 retired from the world's skies forever. In 2013 this Iran Air unit was the last flying Boeing 747-100, a -100B series to be exact. At that time the crew told me that it was probably continuing to fly for another two years, but less than half a year later game was over. In the clip you can see that a Boeing 747-200 checklist was used and frequent questions were asked. The reason is, that the checklists are the same and thus there was no need to print an extra "-100" one. You can see that the rear part of the passenger cabin was dark and empty on this flight. The reason is that that day this aircraft replaced the scheduled B747SP with the same (smaller) SP crew aboard. In order to make the smaller crew fit the bigger aircraft's needs, the rear cabin was "closed".
Iran Air - The Airline of the Islamic Republic of Iran (Persian: هواپیمائی جمهوری اسلامی ایران Havapeyma'i-ye Jomhuri-ye Eslāmi-ye Irān) is the flag carrier airline of Iran, operating services to 80 destinations. The airline's cargo fleet, operated by subsidiary Iran Air Cargo, operates services to 20 scheduled and 5 charter destinations. Its main bases are the Tehran Imam Khomeini International Airport for international flights and Tehran Mehrabad Airport for domestic flights. It is headquartered on the grounds of Mehrabad Airport in Tehran.
Iran Air is also referred to by its Persian acronym, Homa (Persian: هما), which is derived from two sources: the initial letters of Iran Air's pre-Revolutionary Persian name, Havapeyma'i-ye Melli-ye Iran (Persian: هواپیمایی ملی ایران); and from Homa, a griffin of Persian mythology.
The first 747-100s were built with six upper deck windows (three per side) to accommodate upstairs lounge areas. Later, as airlines began to use the upper deck for premium passenger seating instead of lounge space, Boeing offered a ten-window upper deck as an option. Some early −100s were retrofitted with the new configuration. The −100 was equipped with Pratt & Whitney JT9D-3A engines. No freighter version of this model was developed, but many 747-100s were converted into freighters. A total of 167 747-100s were built. Iran Air was the last airline to use the 747-100 for passenger service.
