What is the maximum take off climb angle of a Boeing 737 MAX? This video is making its rounds on social media claiming to show a 90 degree vertical take off:



One can not tell from the video alone what the angle is.


Does anyone have a third party reference for the actual angle for this video?
What is the maximum angle for a Boeing 737 MAX with typical passenger load?
What is the maximum angle for a Boeing 737 MAX especially configured to maximize the angle?
That’s a wild demonstration but it’s also not a very realistic  barometer performance for typical 737 operations. The video you see there is a high-performance demonstration flown in an air show or a trade show just for the purposes of entertainment. It involves an airplane that has literally been stripped down of any unnecessary parts, no other personnel or cargo on board except for the minimum required flight crew and barely enough gas to get the performance done and maintain day VFR reserve minimums to get them back to the airport.   The climb there was done in about an angle of 50 to 55° from the horizontal.    Even in these conditions a Boeing 737 does not have a thrust to weight ratio exceeding one and as such the aircraft is in fact slowing down. Still it gives an impressive climb to around 2000 to 3000 feet above the airport for the spectators below.
