The narrator mentions the Philadelphia Project. More accurately, this is the Montauk Project and the Philadelphia Experiment, both of which were purported to be delving into creating wormholes in order to transport objects from one place to another. Those rumors are very hard to quantify as being legit, but after years of listening to speculation, both wild and scientific, I think there is something to them. As an example, clearly the US got UFO / flying saucer technology from Nazi Germany, after the Germans studied the Indian Vedas describing flying Vimana. There are also rumors about the Nazi Bell in Germany, where time travel / other-dimensional travel and wormholes were also reported to be under study. As far as being able to cloak an entire planet, I don’t know, and there isn’t enough evidence or leaked documentation to really prove that.
