Pumpelly Oil and its parent company RelaDyne donated $15,000 to the Chennault International Airshow, which takes place May 10-12. The sponsorship helps fund the many aerobatic performances and exhibits planned for that weekend, along with scholarships and grants promoting STEM — science, technology, engineering and math — in Southwest Louisiana.
