    Was a pleasure talking to you! Hope to see you back at Ursa Major soon.
  • @thecogdesigns
    At around 41:20, "That is a sexy looking mount there." Thank you very much! That's my design through and through--made my day!
  • @JellyFicheable
    Very grateful for Ursa Major's openness with Tim here. It shows that these guys are really passionate about what they're working on and genuinely happy to encourage everyone's excitement regarding their engines.
  • @spa.des3
    It's so.... BRIGHT! 47:53 That part actually made me laugh 😂 It was great talking to you Tim, and it's awesome to syou bring your honest reaction to viewers. It's impressive how you intelligently interact with the company despite not knowing the details beforehand. Stay tuned on Ursa; I hope we meet again
  • @obsidian....
    Thank you for giving Tim and Co the access. We truly appreciate being able to see all of this 🙏 . Beautiful facility and engines btw. Seems like you have a great group of people
  • @jas_n
    Tim's excitement about the surprise build, Joe's smile interacting with Tim while he watched the tests, and their shared smiles at the end about the explosion footage is all 10/10
  • @jasestu
    Non-clickbait, well filmed, high quality educational and inspiring content. YouTube needs more of this.
  • @RockinRobbins13
    You are the standard for in-depth, high level reporting on space technology! That was amazing.
  • @jamesengland7461
    I just have to stop the video and sit in awe of this first scene- This company has spent years, quietly working in this engine, and of course they have sales and marketing and press releases, and FINALLY they find a journalist who can see, and understand, and intelligently interact with this design!
  • @FrankPace54
    I've been wondering where you have been Tim, glad to see you have been working on another great project!
  • @electricdawn2258
    Love these 20-40+ guys taking rocketry to the future. Wish I could be there and work for guys like these! Thank you again for the invaluable job you do.
  • @Yutani_Crayven
    I love all of this stuff. Makes me feel like we're in the middle of a real space renaissance with all the new companies making strides and working on things. I don't know how long it will last. But, no more stagnation with the old guard. I love the optimism and all the different approaches, focus points and philosophies.
  • @wingsounds13
    I didn't know that Tim Dodd videos could get better - they've been pretty good already. This one was really fun. Interesting to get up close and personal with several rocket engines. I love the comment on the hydrogen igniter fuel "you look at it wrong and it lights". Yes, hydrogen really LOVES to burn. 🙂
  • @max.lindgren
    What a treat that destructive testing footage they shared was. Not generally something tou get to see, especially not up close like that. And it wasn't just one test either, hats off! Cool place, cool people, excited to see more from them in the future!
  • @danceswithmules
    "It's sooo bright!" "Water towers can fly!! YES!!!!" We love your comments, Tim. Never change.
  • @maskddingo1779
    Very cool. Big thanks to Ursa Major for being so open and welcoming! The engine fail videos were neat to see! I wish them great success! Full flow peroxide engine incoming?!
  • @chtrouvpadnom
    Awesome video. Crazy interesting. English is not my native tongue and yet everything is super clear. Definitely goes deeper than most of docs on rocket engineering and still perfectly understandable from start to end. Huge thanks to Ursa Major for opening their doors, and to the channel for such top quality video.
