You're absolutely right. Oddly enough the physics for the "dropping" actually works in real-life. However Luscafilm screwed it up by saying the bombs are magnetic which now contradicts the real-life physics.



But back to the T-wing. I hated nearly every ship in TLJ because they were all just rip-offs of the original trilogy But the T-wing has perhaps the only original design I looked into his concept art and found that the bombing shaft is detachable. It gets loaded and the the fuselage picks it up when ready. That means this ship has multiple applications. I'm a firm believer that The Millenium Falcon needs to go because Han is gone. I feel Chewbacca should've taken the Falcon and returned to Kassyyk. Had the T-wing been faster it could've been the ship Poe, Finn, and Rose used to find Rey and Luke. That way we would've got character development and a New ship to look at.



Bonus: The Other "new" TLJ designs



Mega-class Star Destroyer-Makes the most since but makes Starkiller Base even more redundant. Also it should be called Supremacy-Class because the Supremacy is the only ship in the classification.



Star Dreadnought- The Executor-class was better



AT-M6-Stupid Name, Stupid concept, Looks like a dog taking a dump



TIE Silencer-Actually another design I liked, looks like a natural progression from the TIE Interceptor. However, it brings up another question, "Why aren't the first order using TIEs based off of the standard TIE Fighter and not the superior TIE Interceptor?"



All the Resistance battleships where just copies of the ones in ROTJ



Sand Skimmer(?)-just a lop-sided Snow Speeder
