I spotted the specially modified "Zero G" 727 aircraft at BKL this evening. According to FlightAware it came in from DTW earlier this week and gave two rides today. This is one of the better tracks, as they ended up over Lake Ontario for their circle tracks.

How many cycles per week do these aircraft usually utilize? I've always wondered how much stress that puts on the airframe and if there is additional maintenance that is required to keep the aircraft certified for such flights.
The website says it's up to 1.8 G's and 45 degree nose up in the climb up from 24,000 feet and does this 12-15 times during each flight. That's a good bit more stress than an average flight but since they are not flying nearly as much as an airliner maybe it's a wash anyway..

Quoting FUN2FLY (Reply 3): NASA Glenn microgravitivy lab regularly does these types of experiments, not sure if it's on this plane or their own.
They have a contract with NASA to do some work for them and NASA also has their own DC-9 that performs their "Zero G" test for them as well. This aircraft, the "G Force One" 727 can be seen at Titusville Airport in Titusville, Florida very frequently.
