Kids in college, stuffing the 401k as retirement looms,just bought an airplane and have to pay it off, catching up ( still ) after a furlough, everybody has their reasons. I did it for one quarter while my wife was on maternity leave, 76 day , 8 day tours, in the mighty XL , and swiftly returned to my 7&7 when she returned to her 737, it was challenging , and exhausting, but it paid well, and God bless the guys and girls on it.
