深海水手 ，算了，他们这些军迷不像我们这伪军迷，说得绝对是对的。你记着 service ceiling 就是最高高度，绝对不可能比这高，打死你都要记着噢。 ：）

特别是：
service ceiling 60,000 ft (18290 m);
absolute ceiling 100,000 ft (30480 m);
能解释给我听吗

请军迷，和这里的“正义芝士”指教一下下面这段话：
maximum rate of climb at sea level more than 50,000 ft (15240 m) per minute;
service ceiling 60,000 ft (18290 m);
absolute ceiling 100,000 ft (30480 m);
take-off run 900 ft (274 m) at normal take-off weight;
landing run 3,500 ft (1067 m) at normal landing weight without brake parachute;
g-limits: -3 to +9
The service ceiling is the maximum usable altitude of an aircraft. Specifically, it is the density altitude at which flying in a clean configuration, at the best rate of climb airspeed for that altitude and with all engines operating and producing maximum continuous power.
Service ceiling (without external ordnance and stores), km 7

This makes better sense since Ukraine government is the only one who will benefit from this event. US investigator should know this as well but chose not to say anything. Common logic in any investigation is to look at who benefits even though it is not a definitive proof.
