That's pretty cool, thanks for sharing.
I flew Tu-154 for about a year and from what I hear about the B727 they are very close. Pilot's airplane, very enjoyable to fly.
In our configuration we had 164-170 seats, we did flights up to 5-5.5 hours without cargo or pax hits, 5 FA's, 4 pilot (nav. and FE). Fuel burn was around 5-5.5 tons/hour. Avionics are steam gauges, GPS steroids.
I was great, just having 4 pilots in the cockpit already makes it a lot of fun
Have fun and stay safe
