Could a plane land inside or on top of another plane in flight? I'm sorry if this is a little fantastical, but I'm just wondering if this type of maneuver is possible in any way. I understand if this question gets pulled. I'm trying to make a little action-animation-cgi and just wondering if this was ever a last-resort option for maybe two planes, maybe one is a bit larger than the other but maybe similar speeds could be maintained for the one plane that is running out of fuel could latch-on somehow.
The airforce used to have Parasite Fighters that could be launched and then recovered by a larger aircraft.

The Space Shuttle was routinely transported on the back of two specially equipped B747s.
