Safer than driving. I assume he’s a pilot and just flies himself? That plane has probably 500-700 lbs of useful load; three 200lb guys (gov + ‘security detail’?) + baggage is going to be near the limit…
That’s a Cessna 172a. It’s a legendary aircraft still in production (and probably the most successful aircraft ever made). Extremely safe and they last forever. The only time these planes crash is when they run into something. I wouldn’t hesitate to fly in it.
