They do let you know.Theres nothing like a B-1 at full-tilt-boogy.
I flew a B-17 for a couple of weeks. In Oklahoma there was a B-1 shooting touch-and-go's with full burners and the whole wings pulled back thing on the downwind leg. Helluva thing to see.
Next stop Dayton. B-1 tied down on the runway next to us workin on the APU. The mornin after the show, all the planes were gone cept us and them. We preflighted and fired up. On check-in we had all four turning (so you can hardly hear, even WITH dave Clarks) and the pilot came on and said "Whats that vibration?". We didnt find anything and he came back on and said "Now I hear a low roar". We looked at everything, all good. I was at the right waist position and looked over at the B-1 and they had it fired up with all four burners going full bore. You could hear it and FEEL it above all the radial noise on the plane.
Amazing.<--(gotta put up the only plane emojie!!!)
