Minimialism is great, so long as the price also reflects that.

To add on this, prediction markets currently put Trump Sr. as 8.5% likely to win the 2028 GOP nomination (electionbettingodds.com). So, I wouldn't take your "he'll be done in four years" as certainty. The market thinks things are far more precarious than you do.

Not true, laminar/turbulent and attached/separated are independent descriptors. Flow can be laminar+attached, laminar+separated (e.g., laminar separation bubbles), turbulent+attached (e.g., the majority of boundary layers on large aircraft), or turbulent+separated.

Aircraft designer here, this is not true. We typically certify to <1 catastrophic failure per 1e9 flight hours. Not zero.

I can't wait for the day that AI is used to expose the fakers en-masse. Previously, they got away with plagiarism through obscurity - no longer. The sooner we can excise these freeloaders from our professional institutions, the better.

I did not go though the grueling process of writing an original PhD thesis, just to share a title with those who plagiarized their thesis.

"Fuel is 20 times more than the passenger weight"

For most transport aircraft, passenger mass fraction is roughly 12%-18% depending on what's included (cargo, seats, etc.), while fuel mass fraction is around 30% to 40%.

So this ratio is more like 2 or 3, not 20.

Passenger weight is absolutely a huge factor (speaking as an aerospace engineer focusing on vehicle design and flight performance).
