Was it ever possible to land big commercial jets from the missed approach point during non-precision approach?
Possible? Yes, depending. Advisable? That's a matter of opinion. I suspect most these days would probably say no unless you did a circling maneuver to another runway. And then many (most?) would say that you have no business circling at less than, say, 800 ft AGL in a 747 or the like.

Restating my first answer: Possible? Yes, for some MAPs, with some aircraft, at some weights, at some airports, to some runways, by some pilots, but not if you HAVE to fly a stabilized approach.


  Was it ever possible....


What was physically possible in the past&mdash;let's say 25 years ago so it's within the context of my experience&mdash;is still physically possible today, so I think what you might be asking is whether it was ever done.

While I don't recall ever having done it myself from the exact MAP, I think it reasonable to accept that it would have been done on occasion by some. Back in the 1990s at the two 747 carriers I flew for, we flew non-stabilized approaches when convenient, especially in freighters. Thus, in-close, down low maneuvering was not the no-no that I get the impression that it is today.

Indeed, the IGS 13 approach at Kai Tak in Hong Kong in bad weather meant you'd be popping out of the clouds a few hundred feet above buildings and then having to make a 47&deg; right turn to line up with the runway. The decision altitude was 600 feet as I remember.
