S 1759: Supersonic Aviation Modernization Act

S 1759 in plain English: This bill would direct the FAA to update its regulations to allow civilian aircraft to fly faster than Mach 1 over U.S. land, as long as no sonic boom reaches the ground. Currently, civil aircraft need special FAA authorization to fly supersonically over land in the United States.

Stated purpose

This bill aims to allow civilian aircraft to fly faster than the speed of sound over land in the United States, as long as the sonic boom does not reach the ground, by requiring the FAA to update its regulations within one year.

Key points

• Requires the FAA to issue or revise rules permitting civil supersonic flight over U.S. land without special authorization.
• Allows supersonic flight only if no sonic boom reaches the ground in the United States.
• Removes the current requirement for case-by-case FAA special flight authorization for over-land supersonic speeds.

Arguments supporters make

• Current rules banning supersonic flight over land are outdated and were written before modern technology that can suppress or eliminate sonic booms at the ground level, so updating them lets innovation move forward.
• Allowing supersonic commercial flights over land could dramatically cut travel times for passengers and give U.S. aviation companies a competitive edge in a growing global market.
• The bill includes a built-in safeguard — supersonic flight is only permitted if no sonic boom actually reaches the ground — so communities are protected while progress is enabled.

Arguments opponents make

• The condition that 'no sonic boom reaches the ground' is not yet fully proven in real-world conditions at scale, and the FAA may be pressured to certify technology before it is reliable enough to protect people below.
• Removing the requirement for special authorization takes away a case-by-case safety review, which critics say is a valuable check before allowing untested supersonic operations in populated airspace.
• The one-year deadline for the FAA to rewrite complex aviation regulations may be too short to conduct thorough safety analysis, noise research, and public input on a significant change to airspace rules.

Tradeoffs

Opening the skies to supersonic flight could speed up travel and spur economic growth in aviation, but it removes an existing layer of regulatory oversight and relies on noise-suppression technology performing perfectly to protect communities on the ground.
