Markoz,

Appriciate bringing to my attention description error,using the term 'Base Pack' in assciation with 727-200.

727 grouping comes as: 727-100 Pro Pack 2.2 size 48.4 MB
                                   727-100 Base Pack 2.4 size 50.7 MB
                                   727-200 Expansion Model 2.2 size 13.1 MB
                                   727-200 Expansion Model 2.4 size 12.4 MB
                                   727-200 Freighter Expansion Model 2.4  size 17.1 MB.

Best result came, using 727-100 Base Pack 2.4 and 727-200 Expansion Model 2.4. This combination solved problems mentioned previously.

Apologize if any incorrect terminologies have been used, that may confuse  readers.
