Also makes the 'you dont need a twin engined aircraft anymore because modern engineering is so advanced!' argument a little awkward.
In my view it is not a 'liitle awkward' but plain wrong. The reason why the F35 should be a single engine design is down to engineering facts not "modern engineering is so advanced".
The engineering facts are that if you can fit a single engine that has enough thrust to meet the spec the aircraft will be safer (in respect of engine failure) than a twin design of the same total thrust.
It was appreciating this in the 70s that made the USN change from "our new trainer must have two engines" to "single engine designs are acceptable" and was one of the reasons why the single engine Hawk became the starting point for the T45 Goshawk.
BTW the first Alpha Jet, Tornado and Typhoon total losses all involved double engine failures.
Of course if you need two engines to get the total thrust that you need for the design you have no option but to put up with the various disadvantges that brings.
