The answer to your question depends on a number of variables. The first is aircraft weight. Empty, you might see 6,000 feet per minute climb at low altitudes. Even heavy, you might get 2,500 feet per minute. Another variable is atmospheric temperature. The normal climb profile for our 757s is based on speeds. 250 knots (287 mph) up to 10,000 feet, then 280-330 knots until mach crossover speed of .74 mach, then at .72-.75, depending on weight and ISA. The heavier you are, the faster the optimal climb speed. It is very doable to get 26,000 feet in 20 minutes

Does it only take 20 minutes to reach 26,000 ft?
Don't know and can't find it.

What can the plane hit while rolling on tarmac to create a huge circular crater? The control tower? Another parked plane which bumped it nose to nose?
So if it was a collision on tarmac the object just vanished after the plane hit it?
It is what it is, the plane hit an unidentified flying object while in the air.

I would not dispute whether or not fowls of any sort could FLY at that altitude, and would never want to make the argument about whether it "could be" a bird of any sort. Rather, could a bird or "birds" make a freaking dent in an airplane like that?????

Got no business getting in front of a plane flying 500 miles an hour.
Bet the bird didn't have insurance either.

It's no bigger than some of the bird strike damage that has been seen (and remarkably smaller than some), which include a few that are just dents in the radome. Planes land with this much damage, and more, all the time (just look at some of the more severe bird strike photos.
