For a jet that is nearly the size of an A300, it can carry less passengers than a MD-90.

Instructions:
Activation group 1-Activates middle engine in tail
Activation group 2+Fire Weapons key-thrust reverse.

Notes:
This would be a competitor to the BAC Three-Eleven if it was built.
In theory, this could be converted to a freighter with a swing tail to hold outsize cargo. Though a swing nose would be easier.
Wait, its passenger capacity means that its merely a larger DC9 with a longer range.
With all three engines at full thrust it can break the sound barrier. However, it was designed to only fly at speeds just below to sound barrier, making it the fastest subsonic aircraft that can cross the Atlantic.
In theory, this aircraft can evade a BUK missile by simply flying higher and faster.
Not that anyone would bother shooting down a commercial airliner flying at 90,000 feet...
