be those of a c-21 military aircraft and that would be the military variant of a leer jet. again, we don't really have any information as to who is on board this aircraft at this point, just being told by the airport as well as the faa that eight passengers currently on this plane, it is circling over the runways, and the fire department in st. louis is standing by to assist. once that landing happens, we know that this plane has been circling since about 1:00 this afternoon. but as far as the reported problems at this point from the faa, saying it is a leer jet 45, reported problems with the landing gear door, it's possible they're spending this time troubleshooting, which is why we have seen it go by so many different times here. this is an emergency situation as you can tell by just all of the crews on the ground there, preparing for potentially what could be a bad situation or perhaps they troubleshoot this, they fix it and the plane gets on the ground safely. >> you know, it is interesting, you did mention this, the c-21, the military version of this
