A number of aviation firsts have been seen here. It was the site of the UK's first powered flight and the public debut of Concorde. The cancellation of the biennial airshow in 2020 was a sign of the turmoil in the aviation industry caused by corona virus.

Two years have passed since the executives went back to Hampshire. For an industry that struggled as much as any during and after lockdowns, the mood among bosses in England is likely to be more upbeat than it would have been.

At the show, aircraft buyers could go on an order bender, according to the analyst. Over the past 10 years, an average of 670 planes were ordered per Farnborough, but 800 potential sales are already in the works.

A potential 300-plane purchase from Chinese airlines would give Boeing a commanding position in the world's second- largest aviation market.

The industry is confident that huge growth is ahead despite the chaos at airports around the world. 41,170 new planes will be needed by airlines and freight companies over the next two decades. The forecast was increased by the company.

Before Covid and before the extent of the crisis over its 737 Max model became clear, Boeing estimated about 140 fewer planes a year. 41,000 new planes would more than double the global fleet of 25,900. Two of the five orders will be from the China and Asia- Pacific regions.

It will be different if planemakers take a confident tone. Aid agencies are concerned about mass hunger due to inflation. The invasion of Ukraine by Russia has boosted the prospects of the defence industry.

Decarbonising solutions for the aviation industry range from unconvincing to totally unproven

The demand for air travel tends to be driven by the recovery in the economy, according to a Boeing vice-president. Demand isn't the constraint anymore. We are seeing a lot of demand as customers travel.

The main issue is supply. Boeing is racing to get regulatory approval for longer and shorter versions of the MAX before the end of the year. Suppliers are complaining about the production rate being increased by the company.

The question of sustainable living is a recurring one at the event. Aviation is one of the hardest sectors to decarbonise due to the fact that planes are only 3% of global carbon emissions. Alternative types of propulsion such as hydrogen or electric motors have barely made it into the sky, despite the fact that sustainable aviation fuel is not sustainable.

With our growing demand for air travel and the growing Asian middle class, the industry can look forward to a lot of sales.
