Undoubtedly. Sure it "can" be done. First, not a good idea to announce to the world you busted limitations. Secondly, corporate jets are not Commercial jets. I flew corporate 7 years before moving into commercial airlines. Dont try and compare the two. Third, i am currently and have flown last 9 years in southeast asia. I am pretty sure i know the ISA temps around here. With any kind of fuel and payload, you are not going to even reach your service ceiling.
In fact thinking about it, this is the hottest period of time in the southeast asia. I have not even come close to being able to fly at my service ceiling past two months.
I now have no doubt. In my mind that if in fact it reached 45,000 feet, it stalled immediately.
More importantly, the attitude "i have done it before" will kill you in this industry. As a safety officer, investigating incidents that never make the news, that attitude was the basis of many many incidents.
When I “busted limitations”, it was with a FAA POI in the right seat and a FAA DER kneeling in the floor between us watching.
