I'm not sure why F-35 fans need to preface all their thrice recycled PR pablum positive program news with insults. A Trumpish inferiority complex, no doubt.
That said, it's been the whiners who have, so far, correctly predicted the delays and increased costs of the program. We'll see how that plays out as the RAF gets intimately familiar with the system's demands, and gets the bill for the mandatory C2D2 upgrade package. And we'll see how long it takes to get to 800 FMS sales. Maybe North Korea will be added to the list now.
Jet engines whine, and they are powerful and essential to aerospace and defense...
