Is FLARM helpful?
From a previous post:
"Say the 100 knots indicated is 134 knots true. Closure rate 268 knots or 496 kph, covering 2Km is about 1/4 a second warning. Just saying."
Uh- I don't think so. 2 m in .25 sec = 8 km/sec = 480 km/min = 28,800 km/hr = 17,856 mph = orbital velocity.
Obviously not a script writer for "The Martian."
"Interstellar," maybe.
