This is suggested to be c/n 201 or 415, but neither is correct. C/n 201 is a DHC-8-102 (short fuselage), and there are significant differences when compared with photos of N599XQ c/n 415 online. Missing are various aerials on the top and bottom of the fuselage, 2 small cameras embedded within the port fuselage at front and rear, plus the trailing edge of the wings are missing the additions on N599XQ. 50201 instead has an extra attachment at the base of the tail, has 2 embedded rear cameras in different positions, is missing the ribbing in front of the rear door and has a large bulge underneath the fuselage. One can assume the large pod is removable but existing photos of N599XQ (without pod) do not show the attachment points for it.
