your apratus flying machine must be approved by a scan device near or at a warp location, it is best to test it yourself, because a warp waits for noone.
a 'warp' is a huge flying machine.
there is a look of danger there is a look of crossing a street full of cars if you ran into them i am sure you would be tossed cookies as an advanced veiw of what you are up against as a cars example might be if it is a timeview the cars would not be able to see you or stop or avoid you but it is a veiw only you do not have to dart across traffic if you are a time traveller you have all the time just come back at two or three and walk across, pee in the road, eat an apple and maybe even lye in it for a minute.
