I wouldn't bet on it being fully electric. Hybrid electric is possible but I'm skeptical on even that.

It's a remote control dildo, isn't it?

Meh.  They've already had an Electric jet:

Speaking of rubber band powered aircraft, I've been watching this guy's videos lately:

Just something very calming about watching them fly, with peaceful piano music playing.

I'm skeptical to the point I gotta ask: If it's a jet, what's the exhaust that propels? Cannot be electricity out the rear, so maybe it's the turbofans that are electric and they supercharge combustion? Dunno

As with any (turbine) jet, air. Fuel is used to spin the turbine. Some additional fuel can be burned in the later stages (afterburner) to compound the propulsion effect, but the main motive force is intake air being compressed and accelerated out the exhaust. Electric motors can do that just as well as hydrocarbon fuel, but you need one hell of a long extension cord since battery energy density isn't even close to dinosaur juice...

Renowned for its ability to go vertical not long after take off.

I mean, I'm not sure if that's a particularly rare ability in military jets, generally, but there's a shiatload of videos on the tubes of the Lightning doing just that, and it does look kind of cool.

I must be old school, I had one in the 1960s!

It'll work if the goal is to have an airplane that takes off and then immediately needs to land.

Sounds like it would make in flight refiling a biatchallenging...
