Wrong.
The F-35 has a higher thrust-to-weight ratio than the mirage and so better acceleration and rate of climb up to Mach 1. However, the Mirage has lower supersonic drag and so can continue to...

Rocket seats are likely to make soot marks. Those marks recede at about 45 degrees much in line with the rocket flame trajectory. There was no fire showing in the video of the jet rolling down the...

Not all probabilistic events are independent. You need to read up on Bayesian probability which played a large part in determining the flight path of MH370.

One of the most memorable features of the Vampire T11 (or Mk35 Australian), apart from its painful discomfort, was that you could fly it quite well without using the control column. The pitch trim...

Two other factors may have played a part here if the wings departed in flight.

Low aspect ratio aircraft with the engines close to the C/L tend to have a high rate of roll and so are easy to barrel roll because it's easy to limit the pitch angles. It's a very different matter...
