No I explained exactly why they are are false. Does a rocket in space push off a bullet or a metalframe?
Quoting: Anonymous Coward 77003244 No metal frame, no apparatus at all, just a rocket working in space:
Measurements made from the video indicate that the booster is above the Karman line and in space during the boostback burn. My telescope has an altitude dial on the side which was previously recorded using a gopro during launch. From my launch viewing site, the telescope is angled up about 40 degrees above the horizon during the boostback burn. This sped-up video is zoomed in the altitude dial, apologies the resolution isn't good enough to read the numbers but you can see where the numbers are marked and they're in 10 degree increments, the video starts at launch (0 degrees) and ends at the end of the boostback burn (40 degrees):

At launch the Falcon boosters are about 22 pixels wide in my camera:

I'm 21.1 km from the launch site and the boosters are each 3.7 meters wide, so that corresponds to an angular size of 0.01 degrees. By the end of the boostback they're only about 3.2 pixels wide:

Given that we know from the launch that a 3.7 meter wide booster is 22 pixels wide in the view from 21.1 km, that means a pixel size of 3.2 pixels corresponds to an angular size of about 0.00146 degrees. The range between my telescope and the booster is therefore about 145 km at that time. Given that it's about 40 degrees above the horizon, then even if we assume a flat earth the altitude above the ground of the booster was roughly 122 km. Let's be generous here and say I could be about 5 degrees off on either side of that 40 degree measurement. Even at 35 degrees above the horizon the altitude (even assuming a flat earth) would be 102 km. At 45 degrees it would of course be 145 km above the earth. So it was somewhere between about 102 - 145 km in altitude, above the Karman line and in space. My video indicates it had no trouble reversing course to come back and land near the launch site. Please show your evidence that the video indicates it was not in space.
