1963-FEB-09 is the date of the B727-100 first flight.
Boeing arranged a global (not RTW) 727 tour in 1963. The event took place from August 25, 1963 till the end of October 1963 and is mentioned for example here and here (map).
The tour was rather long, thus I've tried to set up a shorter RTW route. It starts and ends at KPAE and is mostly based on the original destinations (sometimes in a different order) except the section RJTT - KPAE, which was added to simply complete the round.
As shown here, the RTW consists of 15 legs and takes about 50 flight hours.
727 models are avialable for FS9 and FSX as both freeware and payware.
Well, what do You think about something like an "AirSource B727 50th anniversary RTW" event?
