Taking off with 400kgs equates to 310kgs useable to MLA, at 200kgs per hour, that's 1:33ish, plus a few mins if they'd spent a little time in "loitering" flight, rather than a typical max cont transit, with max cont hovers in between.

The cab in question takes off at 2045 local. Last radar returns: 2222 local. Time airborne: 1:37hr.
But when gas turbine engines starve of fuel they simply stop, they don't make fuss by popping/misfiring do they?
My imagination doesn't stretch to him being in a hover when one engine flames out, followed very quickly by the other doing the same. He finds himself in a zero spd EOL, cushions early and runs out of Nr at height...............
