After being asked to return to Gotham City immediately due to the desecration of their loved ones’ graves, Red Robin stages a rooftop rescue of Batman and Robin in the most dramatic fashion possible in Blackest Night: Batman #2 (November 2009):
This is made all the more impressive when you take into consideration where exactly Red Robin was when he received the call at the end of Blackest Night: Batman #1 (October 2009):
Since Gotham City, New Jersey is pretty close to New York, that means it’s approximately 5832 kilometers (3624 miles) away from Paris, France. Barring the use of a Justice League teleport device, the only way he could’ve cleared that kind of distance that quickly would’ve been with the help of a Batplane III, which has a top speed of 7081 kph (4400 mph). Even then, though, it would have to have been a modified version of the aircraft with increased fuel capacity since its maximum range doesn’t allow for a transatlantic flight without at least one refueling stop.
However he managed to do it, good show, former Boy Wonder.
