What happened

Specialty aircraft developer Archer Aviation's (ACHR -8.12%) stock had quite the upward trajectory on Wednesday. The company's shares rose by almost 15% on the day, in marked contrast to the 0.2% dip of the S&P 500 index. Investors very much liked that Archer showed its wares to a big group of representatives from a host of federal agencies just before this year's Independence Day.

So what

On Monday, Archer held an event with the Federal Advanced Air Mobility (AAM) Interagency Working Group at its flight test facility. The Group comprises experts from agencies such as airline regulator the Federal Aviation Administration (FAA), NASA, and the White House tasked with evaluating products and services aimed at developing AAM. 

The U.S. Department of Transportation defines AAM as "a transportation system that will move people and property by air using highly automated aircraft with advanced technologies in controlled and uncontrolled airspace within the United States. Archer is a potentially significant part of this, as it is a developer of electric vertical take-off and landing (eVTOL) aircraft.

In its press release on the event, Archer said the more than 70 attendees saw a live flight test, inspected the company's Midnight aircraft, and were educated about the company's designs, and its efforts in safety and certification.

Now what

The event, and the press release covering it, is clearly meant to show that Archer has a good relationship with the federal government. As this is one of the most deep-pocketed and (potentially) long-term clients anywhere in the world, the news was understandably greeted very positively. Now, Archer has to deliver on its promise of being a maker of quality next-generation aircraft.
