...‘cause I’d be wondering if there have been any sightings lately of Arnold Schwarzenegger, or Robert Patrick, or maybe Summer Glau.
“The bedroom actually lights up like day,“ says Elaine O’Mansky, who lives in the Stevenson Commons condominium building near Beth Tfiloh. “It’s instantaneous and wakes us up out of a very deep sleep.“
She isn’t alone. Barbara Friedman is Homeowner’s Association president for the area.
She was up late one night sweeping her back patio when she heard the boom.
“I hit the deck,“ Friedman explained. “It was so loud, I thought I was being shot. I literally hit the deck.“

Videotape taken at 3:34 a.m. on April 23 does show a flash of light that lasts a fraction of a second and lights up an area the size of a football field in the middle of the night.
The flash on the tape is accompanied by loud boom that sounds like a crack of electricity or lightning.
WJZ meteorologist Bernadette Woods analyzed the dates, times and weather conditions when the phenomenon occurs.
“There’s nothing coming out of the sky,“ said Woods, who added that weather likely isn’t the primary cause of the flash and boom, but it may be a contributing factor. “The atmospheric conditions could be such that they are supporting the event.“
Cameras have videotaped the event on two other occasions. Police have used the shadows cast by the light flash to determine an approximate area where they think the light source may be coming from—30 to 40 feet in the air in the parking lot between the Beth Tfiloh Community School and the Stevenson Commons condominiums building.»
Police Make Headway In Baltimore Co. Mystery
Actually, there are some intriguing and plausible-sounding theories here. Permutations on a balloon-bomb prank strike me as the most reasonable. Then there’s this (I hope) tongue-in-cheek suggestion:
I believe that the unexplained booms & flashes are the results of event horizons or rifts in time due to experimentations in time travel from a date in the future. When the test is successful then you will see an object or someone from the future. Keep looking.
So yeah—it could be Summer Glau.
