I remember talking to some of the old Eastern guys who said they used to pull the boards and go to flaps 40 coming into Miami when they could with the -100s.. Something like 9 miles from cruise ALT to touch down was the order of the day.
David, remember...we are talking about 1970's...where there was no real push for stabilized approach criteria like there has been in the past 10 to 15 years.

Interesting comment Beave. 9 miles from, say, 350 to touchdown NO way, that is complete BS, its almost a 40 degree descent angle. I simply don't believe them and I've done LOTS of emergency descents in the sim. (one for real in the 757) in several different types of 4 and twin jets. (using flap 40 AND full speedbrake, just think of the hammering the flaps would get, YUK !!) ...........and you cant GO down and SLOW down, to the extent that this descent would require besides, Boeing flight manuals say use of flaps above 20,000 is
prohibited. on all the Boeing types I have flown. These guys were pulling your leg ! Sorry, I just don't believe them !!
Stabilized approaches in British and US flying have been around a LOT longer than last 10 -15 years. I did a B737-200 course at Seattle in 1980 and Boeing were stressing it then. (Chet Ekstrand was my instructor, great chap who instructed the -27,-37 and -47) BOAC were stressing it in the '70s on the VC10 , 707 and 747 (absolutely essential on Concorde when it arrived, ) and the RAF were emphatic about it on the V bombers (Valiant and Victor in my case) in the '60s and on my basic jet course in 1962, stable at 300 feet was required even in the little Jet Provost.
Perhaps we should take this thread to PRUNE !!!
