Should have Googled this in the first place! The entire story can be found at <A HREF="http://airtransportbiz.free.fr/Fleets/SWA727.html";>http://airtransportbiz.free.fr/Fleets/SWA727.html</A> For those not interested in following the link, Southwest wanted to try out the B727 to see if it would work on some of their new routes. Howard Putnam, Prez of WN at that time (and later BN) leased one from Braniff and returned it early at Braniff's request. Long story short, the B727 wasn't the right aircraft for Southwest. However they did lease a bunch of 'em while waiting for their new 737-300s to come down the Boeing line. RT Simpson Phoenix
