Help Eliminate Loud Planes Practicing
Over Alpine

The frequency of small planes conducting training maneuvers directly over the Noise-Sensitive community of Alpine has seen a dramatic increase. As a result, the once serene environment of Alpine is experiencing a decline in quality of life due to the disruptive sounds of jarring loud stalls, dives/climbs, throttle changes, repetitive tight/steep turns, and the constant drone of airplane noise that persists from morning until night. Most of these flights originate from Montgomery-Gibbs (MYF), Gillespie Field (SEE), and Brown Field (SDM) airports.

HELPP Over Alpine is dedicated to stopping small planes from practicing maneuvers over the Greater Alpine area. Our platform raises awareness and encourages data-sharing to highlight the negative impact of these flights. We aim to connect with flight schools and pilots who may not realize the stress and frustration they cause residents.

DISCLAIMER: This does not mean HELPP Over Alpine is against planes, pilots, or schools. Our friends, neighbors, and family members are pilots and instructors. Our concern is the chronic, cumulative, and disproportionate noise generated by small planes practicing maneuvers overhead. Straight-through flights at constant throttle, commercial airlines, military, and public safety flights are not of concern to us.
