How many G’s can a 737 take?
A range of +2.5g to -1.0g may not seem like a lot, but they are actually quite sufficient for the turbulence that your aircraft should ever encounter in flight. For instance, moderate turbulence, even though it may “feel” severe to persons in the cabin, will probably only put a force of about +1.5g on the aircraft.
What is oil gulping?
Rapid change in the oil quantity after power lever movement may not indicate a leak – it may be due to oil “gulping” or “hiding” as more oil flows into the sumps. Bearing failures. Bearing failures will be accompanied by an increase in oil temperature and indicated vibration.

Why is the Boeing 737 made in Renton Washington?
The initial assembly of the Boeing 737 was adjacent to Boeing Field (now officially named King County International Airport) because the factory in Renton was filled to capacity with the production of the 707 and 727. After 271 of the Boeing 737 aircraft were built, production was moved to Renton in late 1970.
