Keady, it sounds like you’re either referring to the 737-900ER or conflating that with the straight 737-900 as the flattened aft pressure bulkhead appeared on the -900ER.
I ran a Featured Map about the 737-900 (non-ER) just over a year ago: Rare Birds: Boeing 737-900 (30 April 2025) - Featured Map - Great Circle Mapper <http://www.gcmap.com/featured/20250430> I’ve been on both the -900ER version and the 737-9 (MAX 9) on IAD-SFO flights. The takeoff roll was just short of eternal and at least the -900ER started off at no more than FL280 before burning off enough fuel to climb a bit, then more later in the flight. It felt even more leisurely than a drive in my 1979 Volkswagen with its stunning 48 horsepower. (I’ve never flown on a straight 737-900.) -- Karl > On Jun 6, 2026, at 12:46 PM, Jack Keady via Mifnet <[email protected]> > wrote: > > i forget who writes these informative articles but Smart News today just > wrote an extensive article on the Boeing 737-900 model. > > I would not want to captain one.
