It's a piece of military aviation engineering so secretive that the people who built it were routinely subjected to lie-detector tests.
An employee who attempted to sell information about it spent nearly 20 years behind bars.
The B-2 stealth bomber is such an important piece of the US Air Force's artillery, one has never been publicly put on display long-term.
Close-up glimpses of the aircraft are carefully stage-managed.
When it was first publicly displayed in 1988, the Cold War era threat of espionage and remained so intense that guests were not even allowed to see the rear of the craft.

For that reason, for aviation die-hards, a glimpse into the cockpit of a B-2 has been three decades in the making.
For the first time in its history, the public have been allowed to see inside the cockpit of a B-2 in action since the first maiden flight of a stealth bomber in 1993.

Dallas-based film producer and radio personality Jeff Bolton was granted rare civilian access to the cockpit of what the UK Defence Journal labels "America's most secret aerial weapon".
“In an era of rising tensions between global nuclear powers – the United States, China, Russia, and North Korea – this timely video of is a vivid reminder of the B-2’s unique capabilities,” Mr Bolton told the Journal.
“No other stealth bombers are known to exist in the world.”

The short clip offers rare lingering glimpses of the instrumentation of one of the US Air Force's 20 B-2s' cockpits - while the craft is in flight.
Spending on the B-2 programme averaged $2.1 billion(£1.6b) per aircraft in 1997.
Its distinctive flying-wing shape and advanced technology allow the two-crew bomber to penetrate heavy anti-aircraft defences.

Despite its slender, aerodynamic form, the bomber can pack a heavy payload - including GPS-guided bombs and thermonuclear bombs weighing more than a tonne.
The B-2 fleet is deployed internationally, and based at Whiteman Air Force Base in Missouri.
