Gilligan said it

"why'd you have to say that, impossible,  why'd you have to say that ?"

BTW, per Heinlein, strap on wings might allow humans to fly: on the Moon

Other than being fun, why mention this ?

Because I've always found it much easier to do a task if I know that it has been done before.  The real pioneers will either fail or they'll spend a lot of time/money on a problem.  It was so much easier to write a keyer program for an 8 pin PIC microcontroller after seeing that the fellows at Embedded Research had already created the Tick keyers.  (I did add my old favorite, the potentiometer based speed control).  After Yuri Gagarin orbited the earth it was easier for NASA to send John Glenn around 3 times.  Similarly when a Chinese astronaut lands safely on the Moon and is returned to the earth the example by NASA in 1969 makes it much easier.  

If someone tells you that it's impossible you might believe them and fall to earth !
