New member here, hi guys.
Qatar is unlikely to use 211-214 as tail numbers. As suggested I suspect these look be the last three of the FMS FY serial and the full ones might be:
5662 09-6211
5663 09-6212
5668 09-6213
5669 09-6214
All military aircraft in Qatar use QAxx as tail numbers, the xx two digits in fixed sequential batches for each type. The C-17A Globemaster is the exception, they do have the FMS FY number small on the nose but are commonly noted as MAA and MAB, an abbreviation of civil registrations A7-MAA and A7-MAB. There is an off change the same will occur on the Qatar Super Hercules. Any more info much appreciated.
