i dont think we are critizing the adherence to the rule....rather we find the rule itself weird....

like the Sully incident.... cant figure out the vests because we were not advised might be a little problematic..... and many airports are near water bodies and some airports are at the edge of a lake or an ocean etc....

i still cannot figure out why if a plane travels within 50 nautical miles they dont need lifevests at all, instead a seat could be used as a flotation device...... seriously i want to see someone demonstrate at 40 nautical miles out in the Atlantic Ocean on a Noreaster holding to that flotation device for 2 hours while waiting for the coast guard

TC sure makes 50 nautical miles sound like a 50 meter swimming pool

Gliding maybe, although I think that depends on starting speed and altitude before loss of power, right after take off I am guessing unlikely (is take off over the lake, a la porter, bet you can't glide to Hamilton) but with no power you cannot presumably do a controlled landing - ditching in water seems a far more likely scenario than taking your chances over the GTA to me (just like the Hudson was way more attractive for landing than Manhattan)

Gliding 50 nautical miles (304,000 feet) from an altitude of say, 39,000 feet would necessitate almost an 8:1 ratio. Most aircraft have L/D (very similar to glide) ratios in the upper teens, implying that it should be possible to reach shore under favourable wind and airspeed mgmt conditions, plus a bit of margin to then find a suitable landing spot. Perhaps an airline pilot could better comment.
