It's a matter of priorities. The plane is an immediate threat; the absence of life saving meds not so much.

I am at the stage in life where I regularly take 'life saving" meds (blood thinner) on a daily basis and when I travel I always take an adequate supply, readily at hand. On a commercial flight I do not use the overheads, but stow a small backpack at my feet. My travel clothes have plenty of pockets, so that necessities can be kept on my person.

At an accident scene, there should be no problem securing aide for whatever meds might be lost....
