what does the red mean?

[v0031]

Frenchman Jean-Pierre Blanchard and American John Jeffries travel from Dover, England, to Calais, France, in a gas balloon, becoming the first to cross the English Channel by air. The two men nearly crashed into the Channel along the way, however, as their balloon was weighed down by extraneous supplies such as anchors, a nonfunctional hand-operated propeller, and silk-covered oars with which they hoped they could row their way through the air. Just before reaching the French coast, the two balloonists were forced to throw nearly everything out of the balloon, and Blanchard even threw his trousers over the side in a desperate, but apparently successful, attempt to lighten the ship.

And I don't think the word however in blue is correctly used here.

Were the trousers thrown out of the balloon?

Gering-ding-ding-ding-dingeringeding!"

[Bleach Blonde Bad Built Butch Bodies for Biden]

Yes.

However should be the beginning of a new sentence. The trousers were thrown out of the balloon. The balloon was too heavy because of the cargo. That's what "weighed down" means.

There's nothing intrinsically wrong with the placement of "however" in this sentence, although it may have been better to place it elsewhere given the length and number of commas present.

Just moving it to the beginning would work, moving '[t]he two men nearly crashed into the Channel along the way' to either immediately after 'however' (which would be my preferred placement) or the end of the sentence.
