Is this how a plane looks like in a 3 minute exposure?

or is it something else?

What happened here?
Yes.
Im not sure, but planes usually are a line of dots because of the intermittent lights of their wings. And you have captured a continuous line.
I guess it is a satellite, but there are three lines and that confuses me (maybe starlinks?). The part that is brighter and thicker is a flash of the satellite, it happens sometimes by the reflection of the sun in their solar panels.
Hope I helped, clear skies!

Yes, looks like a plane. The light streaks can vary depending on height and type of plan or helicopter. The plan might went through very quickly, but the lights are bright enough to saturate pixels.

I totally agree with the mates. If you're doing multiple shoots, then when you stack them to obtain the masterlight, it will disappear from the final image.
But if your doubt is what could let this light traces, helicopters, planes, satellites and of course Starlink "trains" can do that.

Probably an aircraft: Navigationlights (red left, green right) are steady, only the anti-collision lights (white) are flashing.

Plane, not open to debate
Definitely a plane. I’ve watched planes visually as they cross my astrophotography field, and sure enough, I’ll see a similar pattern of streaks across the subframe. Satellites are also common, but the are always one solid line.

Yup, plane. Navigation lights form continuous lines. Any collision lights flash and form dotted lines.
Almost looks like a couple of planes. I get this all the time being, about 50 miles west of MHT - and being right in the flight path ! 
I usually just "blink" them out before stacking. Good luck !

Yes, very common.

Yep, you got some strobes flashing, and landing lights, probably at about 10,000 ft.
plane, rather close.
How can I improve star shapes?
I recently acquired a new telescope and while first light was successful, I am a bit concerned about star shapes in the corners of my image especially as it's not a cheap scope and I am using a small sensor by today's standards. My imaging tr...
Star shapes affected by long exposures; similar image quality concerns.
