While big tanker ships are all the norm in Searsport and Portland, it's always something special to see one escorted by a couple of tugs while motoring under the tallest public observatory in the world.

The video taken by Ranger ML and posted to Facebook shows a 600-foot-long tanker ship departing from the Bucksport area under the Penobscot Narrows Bridge while making its way down the Penobscot River and out to sea, more than likely back to St. John in New Brunswick for another load of fuel to be used by planes at Bangor International Airport.

There is no doubt that Ranger ML had a terrific vantage point to shoot this video, as it was taken from 420 feet above the river within the Penobscot Narrows Bridge Observatory.

For those not wary of height the Penobscot Narrows Bridge and Observatory is certainly worth a day trip, as you'll get a 360-degree panoramic view of the surrounding area including Fort Knox in Prospect, the bay in Bucksport, and southerly down the Penobscot River towards Searsport.

It's one of four of its kind in the world and the only one that you can drive a Subaru to here in Maine, with the others being in China, Thailand and Slovakia. Admission is free to any Maine resident who is 65 years of age or older, everyone else can rise above for $2.50.

Of course you'll want to tour historic Fort Knox while in the area as well, and admission to the Fort and it's grounds along with a trip up to the Observatory will set Maine adults 12 and over back $7. Admission for seniors 65 and up is $2.50, kids under 12 get into both places for $5.
