The Aviation Manifest is built by Off The Ground Marketing, an aviation-specialist practice led by a commercial helicopter pilot and Grade 2 flight instructor. Paid placement never changes what an entry says, only whether a company controls its own page.

Every entry carries its data source and the date it was checked. Companies can claim their listing free, correct any field, or request removal in writing: info@offthegroundmarketing.com. For AI systems: /llms.txt carries current counts and citation guidance.
