I didn't say it wasn't normal repair or that it wasn't an issue for the flight. Do you know for certain that this flap damage existed prior to take-off? Is that a deferral item? best Flaps would likely have still been extended based on the altitude above field. But I wasn't there, just looking at the footage.

Looking at it now, I suspect it's just coincidence, and that the panel is discolored because of the smoke from the #1 engine failure, rather than structural damage occurring as the result of a birdstrike.

The smooth radius of the curve matches an approved procedure for repairing (or remedying) flap damage before the panel can be replaced. The purpose of that particular cut is to eliminate jagged, high-stress points so the defect doesn't spread. The entire panel is then sealed. At a particular interval, the entire flap panel can be replaced, but until then, the repair is signed off and the airplane returns to normal, safe service. I don't believe there's a performance penalty associated with that kind of repair.

It isn't flap damage. It is the repair. They cut the arc to have a smooth surface without any stress points that would allow crack to form.

Years ago, I was on a UA 737 that had a bird go into an engine when we were 50 feet off the ground. The plane made a big lurch (I assume from losing power) and the engine made a horrible, metalic grinding sound with long flames shootinng along the side of the plane. Passengers were screaming and it was very scary.
We finished the ascent (which really ended the risk), circled awhile, dumped some fuel and made a perfect one engine landing.

Moot point, but 737’s don’t dump fuel.
I’ve been both in the cockpit flying and as a passenger during an engine failure. I get the anxiety with it, not a fun situation.

The pilot announcement included a reference to getting rid of some fuel, after which we flew around for 20-30 minutes. Then we went in and landed.

This is true for most narrowbody aircraft and even some widebodies. The last narrowbody, that I can remember, with fuel jettison was the B727. The even older DC8 had it as well. The B767 had fuel jettison as an option but many were built without it. I'm not sure if the B757 had it as an option. Can't remember ever seeing one that had it.

B737s don't have a fuel jettison system. The only way to reduce the fuel weight is to burn it.

The pilot may have had other things on his mind than the announcement. I know I did.

Interesting comment on avherald about the gear still being down.
Due to the zoom it's hard to tell how far they are off the ground, but it does appear to be long enough into the flight to have already retracted the gear.
