Night photos from Delhi Indira Gandhi international airport - the Boeing 777 collection

Continuing our photo essay (see part one) on the night photography at Indira Gandhi International Airport (IGIA), thanks to the support of the kind friends at Delhi International Airport (P) Ltd. (DIAL) and the DGCA, today is the Boeing 777 collection.

The 777 is largest twin-engine airliner in the world, along with being one of the most popular, and the most profitable for its manufacturer, Boeing.

The newer 777-300ER, 777-200LR (both of which form bulk of Air India's long distance fleet), and Freighter variants feature the largest engines in aviation history, the General Electric GE90-115B or -110B1 engines. The GE90-115B, has a fan diameter of 3.25 metres or 10ft 8in. This photo offers a size comparison between the GE90 and the earlier engines used to power the venerable Boeing 747.

The GE90 has a distinct "moaning" sound when it starts. It is music to us plane spotters. Play the video to hear it. Anywhere in the world, if you are within earshot of an airport, or on-board a 777-300ER or 777-200LR flight, keep an ear out for the sound.
