Re: How many drones does it take ...?
That the possibility of a twinjet at MTOW losing an engine to FOD on climbout turns "abundance" into "excessive" for perfectly understandable reasons.
Having guessed that's "maximum take-off weight" and looked up "foreign object damage", the question that naturally follows is whether a twin-engined aircraft at max t/o weight losing an engine as it climbs away from the runway should be anything more dramatic than the engine-shutdown checklist, a lot of fuel being dumped at low altitude before the a/c lands back where it took off? Cos even MJN Air lost an engine on their elderly 737 on takeoff and lived to tell the tale - S3E6 was it? St Petersburg? Not on iPlayer or YT alas.)
