PlaneLists.com (Leading Edge Group, LLC) company, first started out using nothing more than a Sinclair ZX80 (eventually a ZX81) learning how to cram BASIC codes into a 16K memory system. Throughout the years we have built custom relational databases for Aviation Medical Examiners, Aircraft Sales Companies and Dealers, and flight schools. We strive to make our systems as easy to use as possible, but powerful enough to meet your needs. With our Amazon Web Server, we are able to crunch and coalesce data at a rate that we could only imagine in 1983. All of our programmers and designers are either pilots, (Major Airlines and private) or work closely within the aviation community.
