The Tupolev TU-144
Originating in Russia, the Tupolev TU-144 was intended for commercial usage with its space-age look and design. Despite being able to hit a speed of 1,200 mph in no time at all, the plane was also completely unpredictable when it came to its performance, being highly prone to calamity. This meant that would-be passengers skirted around the turbojet. Further, the TU-144 was monstrously loud to the point where people couldn’t hear each other speak onboard. The TU-144 saw its last voyage in 1978 where tank valve failures marked its end.
The ATR 72
Prior to being laid to rest by American Eagle, Alex Murel strongly warned pilots not to fly the ATR 82, which he rightly regarded as ancient in its design and that the entire collection was starting to crumble. He sympathized with how feasible turboprops were when it came to special operations, however, the outdated technology was putting a massive strain on the planes. Out of 508 models, 11 crashed, leading to nearly 200 people losing their lives.
