We apologize... unfortunately we (still) can't accept your browser :( Although the site generally looks good in non-MS browsers, you must use MS Internet Explorer in order to register and submit advertisements to PlaneCheck. During initial site development, the system has been tied strongly to MS technology. However, browser evolution has steadily progressed as well, in particular during the last 2 years. We are adressing the issue, as we think anybody deserves the opportunity to use PlaneCheck as an aviation sales platform. For the time being, if you don't have access to MSIE and would like to add, modify or remove an airplane, please mail us your request. We will take care of it. Sincere regards, Charles Rousseau CEO
