In reply to dread-i:
> But what advantage would there be in flying invisible on your home turf?
Off the top of my head:
- Simulating the enemy in combat exercises
- Being the target for testing new airborne or ground based radar systems
I’m sure there are other reasons.
However, if it was flying low it could simply have been an issue of radar coverage. With complex terrain and conventional (not OTH) ground based radar, it’s perfectly possible to avoid your transponder or a radar reflector getting viably pinged. Been there, done that… Whilst memorably humming the theme from Dambusters and flying low along the centreline of the other Derwent reservoir. The little light that on the transponder panel that shows you’re replying stopped flashing completely whilst we were low to the water in the valley. This F-35 disappeared in lake terrain which probably means it was in a valley.
Given the weird nature of the ejection from an apparently flight worthy aircraft, I also wonder if there could have been a bulk electrical failure that took the transponder offline.
Not the first aircraft to be lost, and won’t be the last. Yet another embarrassing incident for the F-35 though.
