5 years after Equestria appears on Earth (smack bang in the middle of the Atlantic), a joint project between the Equestrian and American governments results in the creation of Equestria's first airport; the Canterlot International Airport (EQX). With its two runways and massive standard terminals and numerous hangars, millions of passengers can travel through it every day.

It is also the home of Equestria's flag carrier airline; United Equestria Airlines. Although despite having pre-WWII, WWII and post-WWII aircraft (the most advanced aircraft in the airline's inventory is the de Havilland DH 106 Comet), it allows comfortable travel from Equestria to mainland America or Europe and back. And EQX allows the world's flag carrier airlines to land at the airport, allowing humans to visit Equestria and see its sights and for ponies to do the same for the human nations.

However, doesn't have a crash investigation bureau. Celestia says that she has, 'full faith in her ponies' to not crash their aircraft...'

But then, an Equestrian Airlines B-24 collides with a China Airlines Boeing 747 over the Sweet Apple Acres, the NTSB are called in to investigate, with the main heroes and villains of Equestria to assist them.

Now join them as they rush to solve each crash before more lives are risked...

A crossover with the hit-TV show, Air Crash Investigation. Nothing more to it.

Enjoy!!!!!!
