In 2017, a Man who was not the apex (I heard that.) decided to build a private jet with great or not so great safety issues. the safety pro was the stopping, the safety con was the stopping. the pro was it's stopping distance, at its top speed of mach 4, this thing had a great stopping distance from 100 mph to 0 mph in 200 feet. but the con about that was it stopped at 25.9 G's of force which resulted in the interior to be red, lots of cremations(of what was left, and lots and lotsof hospital bills ranging from $1.5 million to $8.5 billion. only 2,100 were made. AG 1 for parachute. hope you liked my plane history -GoldenApex :)
