Out of downturn map glitch!

So today on 10.mc-war.com server (not that it matters what server it is, they are all the same) and the game was just about to start and I had jumped on one of the sponges right outside of spawn and the game started when I was in mid air. So the match starts and I go flying into the air and right out of the map I go. So what happened is I continued flying through the air after hitting the sponge and was still going through the air when the game started on the downturn_infect map. When I was out of the map I started to type in chat that I had found a glitch. When the zombies came they saw me and they started to say I had the smart movement mod and others were saying that "jakobreece is a hacker!". I am not a hacker and the only mod I have right now is optifine because my computer when playing on server does not have the best fps. Please fix this glitch and please don't ban me. Thank you for your time,

Sorry, I did not get a screenshot, I was panicking because everyone was constantly typing to me that I was hacking/modding. I can redo this glitch so I can take a screenshot. I will post a screenshot right when I am on this map again. And to the admins/mods out there, I will not abuse this glitch and when I take the screenshot I will get back to the map so it will be fair for the other team.
