Odd sound, off topic

[BFMIN]

Last month on one day there was a REALLY loud "rocket" noise. It lasted about 30~40 seconds. Started suddenly, really loud instantly & diminished slowly (seeming to be "going away") then stopped. This is in the Easton/ Cambridge area.

It wasn't a low flying aircraft not even even a really large one. I lived near Heathrow Airport & this was considerably louder & deeper-sounding than a Concorde takeoff if you've ever heard one.

It started to the East & seemed to go UP & Westwards.
It was loud enough that I went outside to see what it was, but it was cloudy & so no visuals either time.
I checked Wallops, even though it a fair way off, (approx 70 miles) but nothing was scheduled on either day.

I forgot about it till today, at 11:30, when it happened again, exactly the same, so it seems to be on a once-a-month schedule.
Anyone had any idea what the heck it is?

Does it sound like a rocket?

Aliens.

Was it Joe Biden breaking wind? Prince Charles' wife Camilla complained about that when he was in the UK.

Steam power plant relief valve testing?

Steam power plant relief valve testing?

I was about to post the same... I even checked google maps for factories or plants in that area.

Sounds like it could be a monthly test of a blow off valve for a steam or pressure vessel. It would start loud, then taper off. Echoes off houses/buildings might make it appear to start in one direction and finish in another.

Would have to be close by though.

Are we sure it was just wind?

Well...it could have been wet. Only the person who changes his underwear and who does his laundry know for sure.

FIFY

Low and fast Jet Aircraft, coming out of Andrews to Dover.
They had to get some Donepezil- Quick, over to Rehoboth.
They just got turned around because they forgot the Lithium
till they got straight.

Was there a launch from Wallups? Not sure if you’d hear those from your position, but that’s a real thing.

 

[BFMIN]

Nope, it was the first thing I checked. Mainly because I've heard a shuttle Launch at a friends place & that was pretty much what it sounded like.
But no launch flame, no launch announcement & no visual.

Not a lot of close by buildings here. Pretty rural area.

Nope too slow moving.

Do you live near Federalsburg? Restricted Area 4006 starts there and angles down to the SW and SE. PAX River flies lots of stuff in there.

Was whoopi or rosie odonell swiming near by?

 

[BFMIN]

'bout 28 miles away.
Whats the relevance?
