Is my data correct?

If your retire half of the 727 from 2011 - 2013 then that would be 36, 1 per month for the next three years and I understand that each 727 is crewed to 12....and from some post the 727 is undermanned at this time between 90 - 100 pilots? If FedEx is getting 53 more 757 from now until 2016 that's about 9 per year with 8 in the final year and that aircraft is crewed to 10? If FedEx does keep it delivery schedule of the 777 then that would be 6,5,5,3 and 3 from 2011 to 2015. That aircraft is crewed to 40 pilots? Now retirements starting in 2012 are 168, 159, 136, 164, and 158 for a total of 785 retirements for a 5 year period or 18% of the pilot work force. So if you add the numbers for each year starting with the 777+757+retirements-727 for each year

2011. 240+90+0-144 = 186
2012 200+90+168-144 = 314
2013 200+90+159-144= 305
2014 120+90+136-0 = 346
2015 120+90+164-0 = 374

If this data is true, then FedEx is going to be hiring soon. This information does not include early retirements or the FT/DT rules (which I assume on the low end will cause most companies to increase their pilot force by 5% to 10%. It is also my understanding that FedEx is purchasing all of its 757 and not leasing him. Since this is the case, I understand FedEx is having a hard time getting them, is this true? Unless the economy tanks again, I think FedEx is going to be hiring a lot of people soon.
