Which countries banned supersonic flight?

In the early 1970s, the Anti-Concorde Project and opposition led to banning of commercial supersonic transport in Canada, Ireland, the Netherlands, Norway, Sweden, Switzerland, and West Germany. This meant that Concorde routes were restricted, making it even more infamous among airlines.

Fifty years ago, the federal government banned all civilian supersonic flights over land. The rule prohibits non-military aircraft from flying faster than sound so their resulting sonic booms won't startle the public below or concern them about potential property damage.

The major reasons that passenger flights with the Concorde SST were discontinued had little to do with its safety record: It was very expensive to operate (fuel, maintenance, and crew costs), and passengers were not willing to pay a sufficient ticket price for the Concorde operation to be consistently profitable.

About Concorde With a take-off speed of 220 knots (250mph) and a cruising speed of 1350mph – more than twice the speed of sound - a typical London to New York crossing would take a little less than three and a half hours, as opposed to about eight hours for a subsonic flight.

In any case, supersonic air travel for the masses looks like it's genuinely back on the cards. Boom is aiming for the first Overture test flights to take off in 2026 and for the planes to go into public service by 2029.

Such speed didn't come cheap, though: A transatlantic flight required the high-maintenance aircraft to gulp jet fuel at the rate of one ton per seat, and the average round-trip price was $12,000.

And the jet pilots don't feel a sonic boom from the cockpit, just as passengers on a boat don't feel the effects of the wake behind them, she added.

The power, or volume, of the shock wave depends on the quantity of air that is being accelerated, and thus the size and shape of the aircraft. As the aircraft increases speed the shock cone gets tighter around the craft and becomes weaker to the point that at very high speeds and altitudes no boom is heard.

However, there were only three ever built, and the project was eventually retired by the United States Air Force. The North American X-15 may be the fastest plane in the world, with speeds at 4,520 mph and Mach 5.93. It's an experimental aircraft used and powered by NASA and USAF.

Boom Supersonic, the US plane manufacturer, plans to have the answer with its new Overture jet, which is set to transport customers at twice the speed of today's fastest commercial aircraft, and is regarded as the new Concorde.

No manufacturer has yet been able to recreate the days of the Concorde, but some are trying. Denver-based Boom Supersonic is leading the pack with its faster-than-sound Overture jet, already securing over 100 orders from United Airlines, Japan Airlines, and American Airlines.

Concorde used the most powerful pure jet engines flying commercially. The Aircraft's four engines took advantage of what is known as 'reheat' technology, adding fuel to the final stage of the engine, which produced the extra power required for take-off and the transition to supersonic flight.

Elsewhere, the frames at the Smithsonian Museum in Washington and another in Barbados have been preserved to a high standard. Despite the ongoing preservation, none of these Concordes are anywhere close to being airworthy.
