BOEING 747-100 —

This is not a 747-100 but rather a 747-200. The customer number was 257, indicating this 747-257 was built for Swiss, and then came to TWA. Cool picture, though.

This is not a 747-100, but rather a 747-200 with a customer number of 57 for Swiss. Hence it is a 747-257 that came to TWA in the late 80s. It may be confusing that it has only 3 windows upstairs, as most 100s have 3 upstairs windows as they were the earliest products, and the early 200s also had 3 windows upstairs. Boeing gave up the 3 windows upstairs on line number 151, producing the 100 and 200 series with more than the 3 windows.

Great photo. Look at the Sppedbird DC-10 in the background. It would have been fun to walk around the tarmac!

You people are NERDS!! Correction...WE people are nerds!!! ;-) Awesome throwback picture, thanks!

We're aircraft aficionados! Nerds are guys who think they know if a Cessna is running hot or cold spark plugs when it flies overhead!

What is with the "spare" engine? Pardon me if it is a dumb question, but I have never seen this before. Photoshop?

N303TW was a 4 engine aircraft. Photoshop anyone? Get this trash off FlightAware.

@Jeffrey Brooks, please do a Google Search for "B747 Spare Engine Pod." After you look at al of the photos of various 74s in this configuration, come back and offer an apology for calling this trash.

Great blast from the past! 5th engine before the era of big transports. Great times on good ole T-Way!

Sorry, Brooks: As a former crew member on TWA 747's, I can say from personal experience that we sometimes flew with that fifth engine in place, to get it where it needed to go. TW, for example had a maintenance base Paris, and we sometimes ferried the engines there. If you could see the front of the engine, you would see that it had a very large spinner mounted on the shaft. This was to limit some of the airflow through the engine, to avoid overspeeding the engine. For the same reason, we kept our speed down to about Mach .78.
